What steps will reproduce the problem?
1. Run under IE 7 (or IE 8 as IE 7)
2.
3.

What is the expected output? What do you see instead?
It crashes

What version of the product are you using? On what operating system?


Please provide any additional information below.


The problem is there is a typo in StorageImplIE6.getItem()


The fix that worked for me is:

@Override
  public native String getItem(String storage, String key) /*-{
    // clean key
    var cleanKey = $wnd.Storage.esc(key);
    [email protected]::load()();
    return $wnd.ieLocalStorageEl.getAttribute(cleanKey);
  }-*/;

The static field *database* should be non-static; otherwise only the handle to 
the first database created is returned when using the generators.

There's a typo in Coordinates.hasAltitudeAccuracy():

it should be
    return this.altitudeAccuracy != null;
but it is
    return this.altitideAccuracy != null;

What steps will reproduce the problem?
1. We are able to insert a value as blob like below
2. I could see in SQLite Explorer that my blob object getting stored. 
3. Now, on SQLResultSet, we do not have anything called getBlob. We could see 
that only getString, double, float and int are there. 
How do I get the stored blob object?

What is the expected output? What do you see instead?
I was expecting a mechanism to read blob object stored in sqlite database using 
gwt-html5-database api.

What version of the product are you using? On what operating system?
gwt-html5-database v1.0

What steps will reproduce the problem?
1. Compiling any module from sources against GWT 2.3

What is the expected output? What do you see instead?
No compiler errors/warnings.

NOTE: The code will compile just fine in the end, this validation jar is not 
used in any module.

Attached is a patch that will allow the gwt-mobile-webkit storage library to 
work with IE6 and 7. Those browsers do not have localStorage or sessionStorage 
capabilities but they do have an early implementation of localStorage using the 
userData behavior. This patch allows developers to continue to the storage 
engine without reverting to cookies or developing an independent solution to 
deal with these ancient browsers.

http://msdn.microsoft.com/en-us/library/ms531424%28VS.85%29.aspx

I am looking for offline database/storage support. GWT-MOBILE-WEBKIT looks like 
a good option.

But for the past two years, I do not see much activity and developments on 
these libraries. So I am concerned about the ongoing support and developments. 
If these packages are discontinued, could some one point me to some other 
options. The GWT's HTML5 Storage API is very basic and it does not support SQL.

Thanks in advance.

Run the Storage API sample in a Chrome4 browser, or in Opera10.50b1. The 
localStorage is operational, while the sessionStorage is not (see 
http://www.w3.org/2010/01/results-wctmb2).

This 'feature' should be distinguishable in the API by adding 
'isLocalStorageSupported()' and 'isSessionStorageSupported()' to the Storage 
class.

What steps will reproduce the problem?
1. Add a StorageEventHandler to a Storage instance
2. Perform transactions on said Storage
3. No events are emitted.

What is the expected output? What do you see instead?
We expect to have a StorageEvent emitted from the Storage.

Please use labels and text to provide additional information.

What steps will reproduce the problem?
1. Eclipse Helios 32-bit, Win7, GWT 2.0.4 
2. Hosted Mode (I think... Run as Web Application
3. IE8

What is the expected output? What do you see instead?
When IE8 comes to Storage.getLength(), or 
localmail = Storage.getLocalStorage();
    if(localmail.getLength()>0){
.....}
When IE8 comes to the getLength part, it crashes on the client side.

whenever I try to invoke something like

        Object[] arguments = {1};
        tx.executeSql("select * from foo where bar = ?", arguments, callback);

I get an error when running against Safari 4.0.3 (5531.9) of this

"number of '?'s in statement string does not match argument count"

I've tried passing in 2, 3, 4 arguments instead and no joy.

I was going to try patch your DatabaseTest.java to demonstrate the issue, 
but I've not yet figured out how to run your test case as I can't check out a 
proper version of your source code with the build tools etc :)

According to the documentation of [http://code.google.com/p/google-web-
toolkit/source/browse/trunk/user/src/com/google/gwt/core/client/GWT.java#26 
GWT.UncaughtExceptionHandler], we need to catch Exceptions before they can 
escape to the 
browser. The Gears Geolocation implementation for instance 
[http://code.google.com/p/gwt-
google-
apis/source/browse/trunk/gears/gears/src/com/google/gwt/gears/client/geolocation
/Geolocation
.java#69 shows how it should be used].

What steps will reproduce the problem?
Run the Storage test on Selenium (e.g. `ant test 
-Dgwt.hosts.web.selenium=localhost:4444/*safari 
-Dgwt.useragents.web.selenium=safari`)

What is the expected output? What do you see instead?
No JUnit failures/errors (from the StorageMapTest testcase)

What steps will reproduce the problem?
- from onModuleLoad() it works, ie onTransactionStart callback function is 
always called after database.transaction()
- from onModuleLoad (in SzemleOffline.java) I start a new RootPanel using a 
composite Login window (Login.java), from constructor of Login it works
- from onClick event of a buttons of the Login window onTransactionStart 
callback function is not called, but onTransactionSuccess is always called

What is the expected output? What do you see instead?
onTransactionSuccess always should be invoked

What version of the product are you using? On what operating system?
Win XP SP3, Chrome 7.0.517.44, GWT 2.0.4, gwt-html5-database-1.5.1

Please provide any additional information below.
It seems that from events, database.transaction (javascript) does not work as 
it should (HTML5-Chrome error?), because its first callback function is never 
called, or the javascript->java mapping does not work sometimes. I doubt the 
latter one, because onTransactionSuccess is always found/executed. I have found 
no similar problem reported, despite I had searched the internet for it.

What steps will reproduce the problem?
1.run HelloDatabaseSample
2.click 'Add Click'
3.

What is the expected output? What do you see instead?

        return (long) doubleTime();
    }

    private native double doubleTime() /*-{
        return this.clicked;
    }-*/;

What steps will reproduce the problem?
1. Open the HelloGeolocation.html page in Firefox 3.5
2. Click on the 'get location' button
3. Sometimes, you get two responses with a single click

What is the expected output? What do you see instead?
Firefox should respond with exactly *one* call in the callback (either success 
or failure)

What steps will reproduce the problem?
1.when pressing a button on the form that will run an update table query on 
the DB will fail due to invalid count of arguments passed.
2. running the same form on regular mode (without "?
gwt.codesvr=127.0.0.1:9997" in the address line) will work fine.

What is the expected output? What do you see instead?
should update the table

the expected output is a message which appear onSuccess, instead an error 
is thrown and a message which appear onFailure (see attached images and 
code).


What version of the product are you using? On what operating system?

using WTK 2.0.3, app engine 1.3.1 on Eclipse 3.4.0
on windows XP 32it SP3

Please provide any additional information below.

 methods that will use the query are attached as methods.txt.

also an error appears when first loading the page (in development mode tab 
in eclipse) that i could not find it's source, may be connected to this 
problem attached as error.txt

:-) Haha! Closed the issue.

What steps will reproduce the problem?
If ran in hosted mode, calling getInt() on a column with a null value creates a 
HostedModeException. Functions as expected when deployed to server.

Please see attached project.

What is the expected output? What do you see instead?
expected: return a null value, what happens: HostedModeException

What version of the product are you using? On what operating system?
GWT 2.0.4
gwt-mobile-webkit 1.5.1
Win7 x64


Please provide any additional information below.
extract the archive and run the file HelloDatabase-compile.cmd in the 
launch-scripts folder. then run HelloDatabase-shell.cmd. load app, click 
button, check shell window for exception.

alternatively, to see it function correctly, run HelloDatabase-run.cmd and 
navigate to url.

Describe the feature and its purpose:

There are two types of shell scripts right now: One to compile the samples, and 
one to run the 
samples in Development Mode (a.k.a. HostedMode).

There is a need to have a shell script to run the samples in Production Mode 
(compiled).

What steps will reproduce the problem?
1.in the positionCallback call position.getTimestamp();
2.
3.

What is the expected output? What do you see instead?
For Java, DOMTimeStamp is bound to the long type. For ECMAScript, DOMTimeStamp 
is bound to the Date type because the range of the integer type is too small. 
(this comes from 
http://www.w3.org/TR/DOM-Level-3-Core/core.html#Core-DOMTimeStamp)

Great work guys ! i love it ! 

it would be cool if the gwt-mobile-webkit API could reuse the Google Gears 
GWT API under the covers if the browser does not support HTML5's database 
API but does have Gears installed

http://code.google.com/p/gwt-google-apis/

then gwt-mobile-webkit's Database API could become the universal API for 
GWT for databases; be it HTML5 or Gears

Describe the feature and its purpose:
The library would implement the W3C spec http://www.w3.org/TR/IndexedDB/ 
like the Web Storage and Web Database specs are implemented.

Microsoft and Mozilla are *never* going to implement the Web Database spec 
due to its dependency on SQL and/or SQLite. Therefore they submitted their 
own spec called "Indexed Database API" which in summary provides a fast 
searching, asynchronous and transactional API on a KEY/VALUE store.

WebKit is also implementing this API, as of recently:
- http://groups.google.com/a/chromium.org/group/chromium-
dev/browse_thread/thread/82891f1ab423df1d
- http://trac.webkit.org/browser/trunk/WebCore/storage

I have a GWT application that uses gwt-mobile-webkit to access the sqllite 
web database supported by chrome. It works extremely well, except for one 
issue.

If the user clicks on the browser back button, then the database
totally vanishes and my application freezes as accesses to the
database cannot complete.

What do I need to do to make sure that any interaction with history
(within my webapp) does not break access to the database?

Thanks,

   -- Pierre

Currently, querying the local database is quite hard and even less 
straightforward than JDBC. I 
propose to introduce a new method to query a local database, using annotated 
interfaces and a 
custom GWT generator.

The annotated interface might look like this (the example is 'ported' from 
http://code.google.com/p/gwt-mobile-webkit/wiki/DatabaseApi):

@DatabaseService(name="ClckCnt", version="1.0", description="Click Counter", 
maxsize=10000)
public interface MyDatabaseService {

  @SQL("SELECT clicked FROM clickcount")
  void getClickCounts(StatementCallback<ClickRow> callback);

  @SQL("INSERT INTO clickcount (clicked) VALUES ({timestamp})")
  void insertClick(long timestamp, StatementCallback<Void> callback);
}


The interface should be used much like we use an RPC service:

MyDatabaseService service = GWT.create(MyDatabaseService.class);


and the service methods can be invoked like:

service.getClickCounts(new StatementCallback<ClickRow>() {
  public boolean onFailure(SQLTransaction transaction, SQLError error) {
    return false;  // don't roll back
  }
  public void onSuccess(SQLTransaction transaction, SQLResultSet<ClickRow> resultSet) {
    clickedData.clear();
    for (ClickRow row : resultSet.getRows()) {
      clickedData.add(new Label("Clicked on " + row.getClicked()));
    }
  }
});

Thoughts?

Hi, I read most of the deferred binding docs, I read your blog posts about 
mobile.user.agent. It doesn't make any sense, but inheriting MobileSafari 
doubles number of compiled permutations on mobile.user.agent property.

I can clearly see

    <set-property name="mobile.user.agent" value="none" >
        <none>
            <when-property-is name="user.agent" value="safari" />
        </none>
    </set-property>

in your MobileSafari.gwt.xml

Using GWT 2.1.1

What steps will reproduce the problem?
1. Running application in DevMode with latest GWT version

What is the expected output? What do you see instead?
I would expect the service to be generated, get error instead:
Found interface com.google.gwt.core.ext.typeinfo.JClassType, but class was 
expected

What version of the product are you using? On what operating system?
GWT 2.5.1
gwt-html5-database 1.5.1

It appears to be an issue with Google changing some things. Here are similar 
issues with other libraries:

http://code.google.com/p/gwt-platform/issues/detail?id=292
http://code.google.com/p/gwt-dmesg/issues/detail?id=5
http://stackoverflow.com/questions/12630987/found-interface-com-google-gwt-core-
ext-typeinfo-jclasstype-but-class-was-expec

Some browsers (e.g. Opera at the moment) don't implement the Storage API, yet 
they do implement 
the other storage option: the Database API.

In this case, it would be convenient to implement the Storage API using the 
Database API as the 
actual storage.

The result would be a Storage API as primary, broadest-supported storage 
mechanism for web 
applications.

Although not (yet) part of the HTML 5 spec it is possible to detect 
accelerometer / gyroscope events in JavaScript. It would be great if there was 
a GWT wrapper for this.

More info on how it can be done: 
http://stackoverflow.com/questions/4378435/how-to-access-accelerometer-gyroscope
-data-from-javascript.

Oh and the sample site is awesome: http://isthisanearthquake.com/.

What steps will reproduce the problem?
1. Run the Geolocation sample in Firefox3.5 and you see ZERO's;
2. Run the Geolocation sample in the iPhone simulator and you see NULLs.

What is the expected output? What do you see instead?
Expected is that all optionals return NULL when not in use.


Please use labels and text to provide additional information.
Tried the Double wrapper to 'help' get NULL values -- no effect. Conversely, 
unsupported optional 
attributes using standard 'double' primitive type return NULLs instead of 
zeroes...

Compiling a project that uses GWT 2.2 and gwt-html5-database, the following

I spotted this today...

https://developer.mozilla.org/en/Storage

I wonder if its possible to implement the GWT API on top of this for use in 
Firefox/Mozilla?

It would be nice if the location to the manifest template (currently hardcoded 
to "/html5-cache-
manifest.txt") could be specified with a module property like this:

<set-property name="manifest" value="/my/path/to/manifest.txt"/>

What steps will reproduce the problem?
1. Call if (Geolocation.isSupported()), it returns true
2. Call Geolocation.getGeolocation().getCurrentPosition(callback);
Bug: Neither methods implemented in the PositionCallback are called

What is the expected output? What do you see instead?
Expect either onSuccess or onFailure to be called

What version of the product are you using? On what operating system?
Using gwt-html5-geolocation-0.9.5 with GWT 2.2.0 on Windows XP, though I've 
tried on Windows 7 & an iPhone. Safari 5.0.3 on Window XP. 

Please provide any additional information below.
This works on Chrome & Firefox

http://sharemyposition.appspot.com

bodyhtml
/client/7A42A07EB3734AAC7E9D01B5021BDF7D.cache.html:709TypeError: Result of 
expression 
'(Id(),Hd).create' [undefined] is not a function.

it's working properly on my Firefox 3.5.7 and iPhone.

GeographicalArea class contains the Integer radius, which, by definition is 
the radius of the area.  Therefore, a larger radius implies a greater 
potential difference between the min latitude and max latitude.  

Given that the latitudeDiff calculation is "latitudeDiff = Math.PI * 
units.getEarthRadius() / radius * 180d;" The larger the radius, the smaller 
the difference between the min and max latitude.  This calculation should 
change.

1. I copied your example with DataService code in my project but altered some 
data.
2. Then putted "CREATE IF NOT EXISTS" command just like in your example.
3. After that I created few methods with SELECT command and one for inserting 
data in table.
4. For getting data from table I used GenericRow class.
5. I use Windows.alert() for messages in success and failure callback functions.
6. And finally refreshed page in browser.

Expected behavior is to get alert messages with ID of inserted row in database 
or data retrieved with SELECT command.
Instead alert showed me DataServiceException that table which I created doesn't 
exist.

I use Chrome 5.0.375.70 on Windows XP. I tried FF 3.6.3 and Safari 5 but I was 
alerted that Web SQL API is not supported.

The strange thing is that when I call "SELECT count(*)" for that table and it 
always returns me count 1.

Later I tried exact copy of your example code, but I got the same error message 
(no such table 'clickcount').

I need help with this as soon as possible.

Thank
JD

What steps will reproduce the problem?
1. download the storage API bundle
2. try to use it with the sample code provided in HelloStorage.java
3. methods Storage.isLocalStorageSupported() && 
Storage.isSessionStorageSupported() are not in the API.

What is the expected output? What do you see instead?
I would expect the sample code to work.
