Passing Buffer Results to Update Graphics Layer, Nothing displays

Permanently deleted user

Hi All -

I perform a Buffer task on a single point feature, the results are IEnumarable<Graphic>, which I store in the variable 'enumRing1'.

Next I use UpdateGraphicsLayer; The input FeatureSet can be either a feature set or collection of Graphics i.e. IEnumarable<Graphic>.

So I pass in 'enumRing1', select the default Render, run the workflow and nothing displays.

However when I execute "RunExternalCommand" "AddTemporaryMarkupGeometry" and pass in 'enumRing1.first().geometry'

I see my buffer result.

So it appears I'm using UpdateGraphicsLayer incorrectly.  Can anyone shed some light on what I might be doing wrong?

 

Thanks

Tom.

  Hi Tom -

  What a fantastic question.

  It sure does look like there's a problem with UpdateGraphicsLayer not supporting Enumarable<graphics> as advertised, but try casting the collection of graphics into a new featureset.  Use Assign to do this;

  Create a new variable fsBuffer1 as a featureset

  then for the VB expression type in; new featureset(enumRing1)

  Use fsBuffer1 as the input for UpdateGraphicsLayer.

  Good luck

  Tom

  Thanks.  Thought I was losing my mind when passing graphics list to graphics layer and it wasn't showing.
