Buenas Alvaro,

soy uno de los trabajadores del proyecto malaga citysense en TOPdigital. Mi problema es que en nuestro web service recibimos la posicion del mapa como dos datos independientes (latitud,longitud) y el operador llama a position, no entiendo muy bien como funciona, o si tendria que mandar el atributo en uno o modificar tu codigo para que pueda aceptarlo en dos!

Te agradeceria que me puedas guiar sobre esto, gracias!

When following the tutorial,

running this command :
(ENV)root@ubuntu:/opt# wirecloud-admin startproject wirecloud_instance --quick-start

results to this error:

Traceback (most recent call last): File "/usr/local/bin/wirecloud-admin", line 7, in <module> from wirecloud.commons.wirecloud_admin import execute_from_command_line File "/usr/local/lib/python2.7/dist-packages/wirecloud/commons/wirecloud_admin.py", line 23, in <module> from django.core.management import LaxOptionParser ImportError: cannot import name LaxOptionParser

But i could not find any package name laxoptionparser for ubuntu..

What are the web browsers supported by Wirecloud? I was not able to find this information in the documentation.

When user closes widget (select 'Close' button in top right corner of the widget) it should be possible to detect this event programmatically.

In addition, the same principle should be applied on the rest of the widget manipulation options (e.g. minimize, maximize, full dragboard, exit full dragboard, extract from grid, snap to grid, rename).

How can I wire an application consisting of more than one tabs containing one ore more widgets with the same content and functionality? Is it possible to define a widget outside a tab so that ist is always visible when the user selects any tab?

Newest versions of WStore supports what is called open offerings (offerings that are free and don't require registration, so can be used directly).

This is a regression due to the new search code.

Whoosh supports search query corrections, use it for provide user with corrected queries when searching available resources in the local catalogue of the user (and for external WireCloud catalogues).

This ticket has nothing to do with adding support for correcting search queries made to the FI-WARE's Marketplace & Store, as they need to provide that support via API.

This ticket is only for tracking that category metadata can be added to mashable application components descriptions and WireCloud handles it correctly.

In a near future, this metadata will be use to allow browsing resources using those categories in the user interface, but this will be tracked using another ticket.

Sometimes there is not a reason to show a title near the widget, WireCloud should provide a way for displaying widgets without a title to be able to create clear/simple dashboards.

I have pure JS\HTML app that use AngularJS. Can it be hosted as a WireCloud widget?

I have an application consisting of various tabs with the same widget on more than one tabs. In wiring view I see all instances of this widget but I cannot differ which of them belongs to which tab. Is it possible to rename these widgets so that the correlation to the tabs will be recognizable?

is pagination avaible in Wire Cloud NGSI API? how can I use this new option in Wire Cloud?

It would be useful for a widget developer to have a private versioning for widgets in development.
Namely appending "-dev" to version number in config.xml should enable same version widget overwrite even in the case of different widget content (i.e. different hash).

Since yesterdays update to latest "develop" branch version, I get the following error for all my widgets:

After switching from the column layout to the grid layout, the widget height is terribly long.All other widgets on the workspace will be kicked to the bottom of the page, which means a lot of scrolling to bring them back in the right position.

Example:

Height after adding in column-layout:

Height after adding in grid-layout: (Scroll bar)

The available API for the Object Storage API at FIWARE Lab has changed and now widgets/operators using the binding provided by WireCloud are failing.

At least the listContainer method is failing, see the following question on StackOverflow for more info, but other maybe other things are also failing.

Create a new repository for the WireCloud image for docker: https://github.com/Wirecloud/docker-wirecloud

And provide one or more compose templates for using it.

The upload system returns an error when a user upload a widget/operator that has a preference with an empty default value.

When attempting to push data over a widget's endpoint and that endpoint is not defined in the config.xml file, an unhandled exception (correctly) occurs:

Uncaught TypeError: Cannot call method 'propagate' of undefined dcac64b2b132.js:812

This behaviour is fine and not an error per se, of course, but I do have a feature request concerning these cases:

When attempting to push or register callbacks using endpoint names that are not defined, the error should be cought by the API itself and pointed out in the JavaScript console or a modal pop-up. I propose this for two reasons:

1. uncaught exceptions will stop the execution of the script, which can be inconvenient in some cases; and more importantly
2. in my opinion, the error message (Uncaught TypeError: Cannot call method 'propagate' of undefined) does not properly reflect the underlying issue that one attempts to use and endpoint that is not defined. This can be non-trivial for developers to identify.

Currently, workspaces can be public or private. It would be great to extend that support to being able to share workspaces with concrete users and groups.

When uploading a widget to the local marketplace there is a request http://<my_hostname>/wirecloud/catalogue/resources?orderby=-popularity returning HTTP 400 (BAD REQUEST) with error description: "Orderby not supported".

• Django 1.7 is going to drop python2.6
• Almost any recent Linux distribution comes with python 3

During wirecloud tests temporary directories are created but noone is removed. This will cause /tmp to consume disk space for nothing on systems that don't reboot daily (like servers).

Best practice suggest to employ TempDirectory [1] fixture as decorator or as instance attribute in conjunction with unittest.TestCase.addCleanup() function during setup to track used resources, so to free them automatically during teardown phase (even when setup fails)

I integrated Wirecloud with Apache as described here

Everything is working fine except uploading and deleting widgets to/from the integrated Marketplace.
I get the following error when trying to upload a widget:

When running Wirecloud in Django's internal web server, uploading the same widget works just fine.

Before installing WireCloud on Ubuntu you must install these packages

libxml2-dev libxslt1-dev python-dev

otherwise command

 $ sudo pip install APPS-Application-Mashup-Wirecloud-x.x.x.tar.gz

fails

Tested on Ubuntu 12.04 64bit

What is the recommended workflow for widget development? The tutorials I see online seem to invite developers to zip-rename-upload the developing widget to test them out.

Is there a way to develop and test the widgets by circumventing all this zip-upload business? Or has anyone developed editor plugins to automate this process?

Please allow passing parameters from the surrounding Webpage into Widgets.
This means, if you embed a workspace as IFrame, you can add additional parameters. E.g. currently
<iframe src="<url_to_workspace>?mode=embedded"...> may be extended <iframe src="<url_to_workspace>?mode=embedded&user_id=1"...>

The given parameter user_id is then passed to, for example, an operator which accepts a specific parameter as input.

Currently this is prevented as the operator's URLs do not include such GET parameters.

The request that returns the details of a resource belonging to a public workspace , returns a 401 .

It is only accessible using the credentials of the owner.

https://wirecloud.conwet.fi.upm.es/api/resource/vendor/name/version/description?include_wgt_files=true

An Exception occured in my widget, but the log doesn't told me what the problem was
It just say:
Widget has not registered a callback for this input endpoint

Although I implemented the 'input' endpoint
I found out that the problem was a forgotten brace.

It wasn't a custom instance of the filab, it was the one which is online.

Currently, I have to serialize all data transferred between Wirecloud widgets, which is very performance consuming. Is it possible/planned, that input and output endpoints can accept data "by reference" instead of "by value"?

Would be great to include into WireCloud an API for using the API provided by Cosmos(Hive) remotely.

This requires changes in the configuration of the Cosmos instances, WireCloud is not going to be able to connect to Cosmos instances using TCP mode in the HiveServer2 as it's not possible from browser.

JavaScript API can be created following this tutorial.

See the HiveServer2 documentation for more information.

When making the GET request for retreiving current values of the preferences (for example, the preferences of a workspace), WireCloud doesn't report the details of the preferences that has not been modified (they are using the default initial value).

It should be possible to define custom user tutorials which are accessed from User menu (upper right corner) -> Tutorials or from the Welcome screen (empty workspace).

This functionality would be used together with 'User template' issue (#50) to provide instructions for user first login.

Currently, Wirecloud doesn't ask the user if she really want to remove the tab. Other operations ask for confirmation (for example, when removing workspaces).

From this stack overflow question.

The docs say that Python 2.6 is supported, but platform/workspace/utils.py contains dictionary comprehensions, that are only supported by Python 2.7+

When users log in via an OAuth2 service, they have the option to don't allow WireCloud access their information. In that case, WireCloud returns a 500 Internal Server Error.

We think about sending onclick events to a tab element to switch between tabs programmatically. The tab elements cannot be accessed directly because they have no id or name. Is there a possibillity to realize this?

It should be possible to define 'user template' by using admin Wirecloud account in order to provide pre-configured Wirecloud environment with specific welcome screen, widgets, mashups, tutorials, language, etc. Wirecloud admin would be able to assign 'user template' to a new Wirecloud user.

In addition, Wirecloud should provide API which could be used by other applications to programmatically assign user templates to new users.

Even though the workspace is public

If the description of an input or output endpoint in config.xml contains more than 250 characters, there is an "HTTP 500 - Internal Server Error" reported when uploading the widget. This results from a Postgres exception on the server because the db field for the description is limited to 250 chars. Is it possible, to eliminate this restriction?

Is it posible to upgrade an existing wirecloud instance to a new wirecloud version without losing all data?

When the vendor name in config.xml contains a space character, this is converted to %20 and then to %2520 in the widget url (since % is converted to %25). After that, the url is not valid anymore.

Current database search engine has some drawbacks:

• Doesn't provide autocompletion assistance.
• Doesn't play nicely with translated resources.
• Makes hard to extend the search engine features and makes the search engine depend on ad-hoc database relations.
• ...

I think that reimplementing the search engine using whoosh should improve this situation.

Hi there, I'm trying to familiarize myself with Wirecloud starting with quickstart option as it is shown in the documentation.

wirecloud-admin startproject wirecloud_instance --quick-start

But i got this error:

mod_wsgi (pid=19541): Exception occurred processing WSGI script '/opt/quickly/quickly/wsgi.py'.
Traceback (most recent call last): ...
ImportError: Could not import settings 'quickly.settings' (Is it on sys.path? Is there an 
import error in the settings file?): No module named wirecloud.commons.utils.conf

I followed the steps of Administration and Installation Guide and have configured my local instance over Apache 2.4 server

PD: sorry i dont know how to assign Doubt label.
