eLayerList Widget

NolanAlbarelli — Wed, 27 Aug 2014 13:30:24 GMT

I have queried a service to just show a few ships of interest. The problem is, when I try to expand the "+" next to the layer label in the eLayerList Widget, it makes the layer list essentially crash. Has anyone else seen this? When I try to expand the layer, I can see the sublayer appear at the top of the layer list behind the first operational layer. At that point, no layers can be turned on or off and the viewer requires a refresh to work.

This must be a bug, right?

Thanks!

Nolan,

Yes that explains it. You can not query a layer in the url for that layer like you are attempting. To limit the features that are returned by a layer in a map service you should be using the definitionexpression attribute on the layer tag using either a layer type of (type="feature") if you want to just add the one layer from the map service or something like this if you want to keep the layer type as dynamic:

<layer label="USA Federal Lands-Reservations" type="dynamic" visible="false" alpha=".7" url="http://maps1.arcgisonline.com/ArcGIS/rest/services/USA_Federal_Lands/MapServer"> <sublayer id="2" definitionexpression="AGBUR = 'BIA'"/> </layer>
