PolylineClip.cs and this.boundary.SpatialReference

BKuiper — Thu, 22 Aug 2013 18:41:24 GMT

Hi,

I ran into an issue where Clip within PolylineClip.cs throws an NullPointerException. This only happens when i run with AcceleratedDisplay DISABLED. The layer is loaded fine when AcceleratedDisplay is turned on.

this.boundary.SpatialReference is null on the construction of PolylineClip.cs and therefore crashes on the second line of the Clip method where the Dateline is being retrieved from the SpatialReference.

The error seems to only happen when i have three specific layers loaded at startup. If i disable anyone of them the nullreferenceexception doesn't occur. I load a baselayer and two graphicslayers (one just polylines and one with polylines and polygons).

I hope this is helpful

*kick*

i'm kicking this thread back up just to make sure that the ESRI team doesn't miss this error. Not critical for us at the moment, but something you might want to look into.
