When a webmap has incorrect layers, the viewer simply stops rendering the toolbar and the widgets. No error is shown to the user, just an incomplete set of tools and map.
Apparently this occurs if you save and share a web map pointing to some map item like a feature service, then delete de map item from arcgis online (not from the web map).

The arcgis online viewer displays a detailed message: 'Layer XXX not found'. How could I customize the javascript viewer to handle that? All I could find was a .createMap passing the webmap id in main.js but didn't find any way to handle specific errors other than map not created at all, because in this cenario the map is created, just one layer isnt rendered.

after changing the printTask url in commonConfig.js to other, for example, "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task", the printwidget still use "utility.arcgisonline.com"

it would be a good idea to mention in the readme for this repo that the AGOL viewer has now been replaced by..
https://github.com/Esri/Viewer

i can take a stab at this doc change if it would be helpful.

Please add a comment to the commonConfig.js and the readme.md files explaining the purpose of the queryForOrg parameter. Many users do not know that changing the value to false allows the app to use non-ArcGIS Online services.

Hi Kelly,
Would it be possible to add a query widget like the one in arcexplorer online?

The screenshot referenced in the README.md seems to not be accessible:

The export options JSON parameter is missing from the request when printing with any template. Other templates still successfully print, but if the MAP_ONLY template is chosen (by first adding it as an option in the printLayouts in the index.html file), the request will fail with the error:
ERROR 001305: Missing or invalid 'exportOptions' property in WebMap; cannot derive a size for the output image. Failed to execute (Export Web Map). Failed to execute (Export Web Map Task).

The attempted remedy of hard-coding the exportOptions parameter either in the index.html file or in the layout.js file (around line 1000) also fails:

exportOptions = {
'outputSize': [
800,
1100
],
"dpi": 96
}

The JSON request adds these parameters, but the outputSize dimensions are set to null, resulting in the same error message:

{
"exportOptions": {
"outputSize": [
null,
null
],
"dpi": 96
}
}

To fix the JSON request, the null values can be changed to [800, 1100]:

{
"exportOptions": {
"outputSize": [
800,
1100
],
"dpi": 96
}
}

Hi

I want to add my base map.But i am able to see only webmap id which i didnt have.
I wan to add map like this
var myMap = new esri.Map("mapDiv");
Where to write this code??

If secured services are used in the application, the alwaysUseProxy property in app.js needs to be set to true. It would be helpful for the user if this is documented in the readme file.

i have downloaded basic viewer template its working fine with webmap id. but how to modify script to take webmap layers.

I started a new issue since the last one that referenced this issue has been closed. I'm using the basic viewer template. I have changed the URL of my custom printTask in several places, both in commonConfig.js and printpage.html (printurl variable). When I save the changes and open my app, the app is still using the out of the box print task
//utility.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task

I have searched exhaustively for another place where the URL might be defaulting, and could not find anything. I have added my custom print task as an item in ArcGIS Online and it works with my other non-custom AGOL web applications, so not sure why my app is not reading the URL.

I'm unable to get the page to load. Developer tools shows the following error:

GET http://js.arcgis.com/3.8/js/dojo/dojo/templateConfig/commonConfig.js 404 (Not Found) init.js:39
Error {src: "dojoLoader", info: Array[2]}
init.js:40
src: dojoLoader init.js:41

.

The ArcGIS Online viewer opens up a set of functionalities when you click the arrow near the layer name.

One of these functionalities is 'Filter'. This allows users to create custom queries specific to their needs, like: all crimes that happened in a specific district that were tagged as robbery.

I didn't find such functionality out of the box in this viewer, any directions on how to implement a 'Filter' one?

Possible I am missing the obvious.

Do you state in your readme where the configuration parameters are to be set - e.g. a specific file and section of the file?

We had a user at UC request the ability to hide sublayers on their basic viewer app. They don't want to expose the map's sublayers in map services.

Hi, I haven't had much luck adding customizing the basic viewer with another geocoder.

My goal is to replace the default Esri World Geocoder with my own.

When I edit the commonConfig.js file and refresh the app, it looks like the viewer's still pointing at the default geocoder. (Screenshot attached)

I saw this comment in the layout.js file: "only use geocoders with a singleLineFieldName that allow placefinding". I added a place name alias locator service to my composite address locator, but it didn't make a difference. My locator already supports single line fields.

At this point I'm not certain if this is an issue with the viewer, if I'm getting my syntax wrong, or if the viewer has an issue with my own custom geocoder?

How can I add my own layer to the map?

I can't seem to get the sub layer toggle functionality to work. I'm fairly new to the API, but have understood the configuration thus far. Do I have to add my own custom layers to achieve this or can I still just use the generated webmap ID? Cheers
