Hello I have set up an workflow that call an geoproccessing tool and the tool return an GPFeatureRecordSetLayer.

I want to present this in the viewer an add the tool: "AddTemporaryMarkupGeometry" with the parameter: gpResult.FeatureSet.Features()

gpResult are a parameter and the return of the geoproccesing.

Get this error messages: The calling thread cannot access this object because a different thread owns it

Some tip?

 

Best regards

  I experienced something alike.

  Try creating a new variable and use the ASIGN activity to assign gpResult.FeatureSet.Features() to it.

  Then use this new variable as input into the AddTemporaryMarkupGeometry activity instead of directly using gpResult.FeatureSet.Features()

  Also be sure to pass the correct parameter type to the command. The AddTemporaryMarkupGeometry command takes a single Geometry object as its parameter. Where as gpResult.FeatureSet.Features() will give you an IEnumerable<Graphic>.

  Hello thanks for tip Ryen and Sune

  I tried the Command Name AddFeatureSetsToSelection,  and then I got the result up in the table view. But I also want to present the same result in map. That command can I use then?

  I am having similar issues ("The calling thread cannot access this object because a different thread owns it.") when I simply try to NEW() a SimpleMarkerSymbol (or any symbol for that matter), from within a workflow.

  [ Assign ]

   

  myLineSymbol = new Esri.ArcGIS.Client.Symbols.LineSymbol()   << crashes the Workflow

  .. and myLineSymbol is declared as an Esri.ArcGIS.Client.Symbols.LineSymbol , too.

  Frederic, 

   

  I'm getting the same error when trying to set the renderer.  Did you find a solution to this?

   

  Thanks,

   

  Stephanie
