Highlighting

Jason Hannigan

I can't seem to get any highlight to work with a workflow on Silverlight viewer v1.7

I've use the "RunExternalCommand" to create, select, and highlight

 

 

CreateHighlightLayer

 

SetActiveHighlightLayer

 

HighlightEsriFeatureSet

 

 

The workflow runs fine, and it ends up zooming to the selections found, but it doesn't display anything. Is there some way i have to activate highlights or am i missing something?

    here's the XAML text if it helps.

    I found the culprit. after debugging everything imaginable.. I found our my rest service was broken. Regardless of if i asked for a query to return the geometry it would not, returning only the fields.  I had to recreate and republish my rest service (double checking it was still returning the geometry along the way) and it works now. It was a strange case since it appeared to be working, there were no errors being displayed, it was just as if the "returnGeometry" flag was stuck on false.

    Hope this can help out someone else in the long run!
