AddToCollection<Graphic>

Am using a ForEach<Graphic> loop to funnel the results to a lengths task.

The AddToCollection activity has a collection named "graphic"

How do I take this singular element and convert it to a featureset, so I can display this one element amongst the others in a different colour?

Or would there be a better solution for doing this?

  Could you explain what is is you want to do exactly? The results of a Lengths task is a List(of Integer), I'm not quite sure why you'd want those converted to a featureset.

  Berend,

  When my workflow runs, my clients could indeed pick one or many, many sidewalks with the capture graphics activity. Although I do select on the sidewalks that were processed through the query activity, I wanted to be able to uniquely colour the exact sidewalk that is being processed by the lenghts task at that time. 

  So, inside my foreach feature loop, I recolour the sidewalk segment by creating a mini-featureset inside the loop.

  That way, when the measurement is displayed, my client knows exactly which sidewalk segment is being processed.

  How this was solved was that the "AddToCollection<Graphic> activity, the collection parameter I used this ....NewFeatureSet.features and thus uniquely identified that specific segment.

  I see. In that case I think I would use a RunExternalCommand activity with AddTemporaryMarkupGeometry as Command Name and the graphic's Geometry as Command Parameter.

  Use ClearTemporaryMarkup to clear the previous sidewalk.

  Berend,

  Yes, that would work too.

  Thanks for your help....Walter
