JavaScript API 2.7 vs. 2.8 - FeatureLayer.applyEdits

Anonymous User — Mon, 02 Apr 2012 19:39:47 GMT

Hello all,

Has anyone had any issues running applyEdits on feature layers since the update to version 2.8 of the API? I find that with versions 2.7 or earlier, I could execute applyEdits() on a FeatureLayer object, even if the layer hasn't been added to a map, with essentially two lines of code:

var featureLayer = new esri.layers.FeatureLayer(url,{<opts>});
featureLayer.applyEdits([newGraphic],null,null,function(addResults){ // verify results });

However, when I try this in 2.8, and if the layer is not already added to a map object, I get an error message that looks like:

----- TypeError: arr is undefined http://serverapi.arcgisonline.com/jsapi/arcgis/?v=2.8 Line 14 -----

I've found that the only way to work around this is to actually add the layer to the map (even if I don't necessarily want it displayed to the user), then run applyEdits...but this makes things a bit more complicated. Basically, after creating the layer, I need to connect to the onLayerAddResult function and run applyEdits within that callback event...when the callback is fired, I can remove the layer again (if I don't want to keep it in the map), and disconnect from the event. Once that is setup, I finally add the layer to the map and wait for the callback to execute.

var featureLayer = new esri.layers.FeatureLayer(url,{<opts>,visible:false}); var listener = dojo.connect(map,"onLayerAddResult",this,function(layer){  if (layer==featureLayer)  {   dojo.disconnect(listener);   featureLayer.applyEdits([newGraphic],null,null,function(addResults){ // verify results });   map.removeLayer(featureLayer);  } }); map.addLayer(featureLayer);

My guess is that this is a result of one of the two following fixes/enhancements listed for version 2.8:

NIM079205: Enhance feature layer to support editor tracking

NIM079209: Do not serialize non-editable fields from a feature layer in applyEdits

If it's the latter, then I would suspect that the error is happening because the FeatureLayer has not yet retrieved the metadata from the FeatureLayer's REST service, and that this only happens after the layer gets added to a map.

Should it still be possible to applyEdits on a layer that is not added to a map object first? Alternatively, is there a better way I can do this?

Thanks for any advice.

Yes. This still works for me at 2.8: http://jsfiddle.net/aZjHR/

Can you post a more complete code sample that shows this problem?

I'm not sure that the example you're linking to is comparable - in my case, the FeatureLayer points to a REST url. In the sample you linked to, the FeatureLayer is being created from an empty FeatureCollection object that has no association with an ArcGIS REST feature service.

I'll try to put together a sample, but I don't have an ArcGIS service that I can easily open up to the public for applying edits...any ideas of what I could use for a substitute?

Actually, if I take that exact sample, and substitute these lines:

        featureLayer = new esri.layers.FeatureLayer(featureCollection, {
          id: 'flickrLayer',
          infoTemplate: popupTemplate
        });

with this:

        featureLayer = new esri.layers.FeatureLayer("http://localhost/ArcGIS/rest/services/MapName/FeatureServer");

Then I click run in the jsFiddle interface, I can reproduce the same error mentioned above (in Firefox/Firebug). So if you have a FeatureServer that you can drop into that spot in your code, you might be able to see the same thing I'm seeing.

I will take a look and get back to you.

Has anyone been able to confirm this issue yet, or are there any recommended solutions besides my workaround outlined above?

Hi Mike,

Apologies for not getting back to you.

This is indeed a bug. When a feature layer isn't added to the map, the edit is successful, but internally the applyEdits success callback is trying to draw the feature. Since the feature layer isn't added to the map, this isn't possible. We'll try to get a fix in the next release. Until then, please use the workaround you outlined above. I'll also make a note to post back here once I have a public bug tracking ID.

I have exact error that prevents me updating from 2.6 to 2.8.

Look forward to seeing this fixed in next release.

Code break here

var attr = { "USAGE": status, "ACTION":"update"};

var newGraphic = new esri.Graphic(Point, null, attr, null);

featuureLayer.applyEdits([newGraphic], null, null);

Can you confirm that applyEdits fails ONLY when you haven't added your feature layer to the map? If your featureLayer has been added to the map, and applyEdits is failing, that is a different issue.

Derek,

I can confirm that applyEdits fails on standalone tables as well. A table that is added to the published document, prior to 2.8 could be brought in as a feature layer and operated on. Needless to say, adding this layer to the map is meaningless so the above solution does not work. When playing around a bit, if I set MODE = Snapshot on the tables featurelayer, the error I get is object does not support setAttributes, however, removing that setting gives me the error that states something about the geomtery.

Hope this helps, until there is a fix, I'm stuck at 2.7.

Thanks

Hi Harold,

Thanks for the additional info. We are looking into a fix.

Yes, that's a layer won't add to map.

"Can you confirm that applyEdits fails ONLY when you haven't added your feature layer to the map? If your featureLayer has been added to the map, and applyEdits is failing, that is a different issue. "

Thanks for following up. This will be fixed in the next release of the API.

Thanks for following up. This will be fixed in the next release of the API.

Has this been fixed?

I'm trying to apply edits to a feature layer (without adding it to the map first) and I get "Uncaught TypeError: Object #<Object> has no method '_isWrappable'".

Thanks

We fixed this in 3.0: http://help.arcgis.com/en/webapi/javascript/arcgis/help/jshelp/new_v30.html

As of 3.10, is this issue resolved for tables accessed as FeatureLayers?

I am facing this issue with my tables...
