GraphicLayer not displaying resulting FeatureSet

RickBaker — Tue, 16 Nov 2010 19:39:51 GMT

I am attempting to display the results of my featureset in the GraphicsLayer but nothing is displaying. I know the query is working because of the count on the features in the resulting featureset.

What happens if you don't set myGraphicsLayer's symbol? Can you also double-check that the layer's shape field is published so that the geometry is being returned?

Yes, that worked! I removed the GraphicsLayer symbol setting and now I see the graphic layer displayed in the apparent default symbol. Apparently something wrong with my "infoSymbol1" definition??

thanks for the help,
Rick

The InfoSymbol only works with point data. Are you returning polygons?
