Description

The following stacktrace is generated by uDIG when trying to add a WFS layer with a geometry type that is named "the_geom". The same WFS layer renders in uDIG 1.1.1.

STACKTRACE:

I hope there is more to it than simple the name the_geom? Can you check the describe feature type for your WFS? Something is telling uDig to query for "geom" ... what could it be?
Capabilities? SHould list the feature types ...
Using the feature type name to query the DescribeFeatureType operation should give you an xml schema (ie XSD file). Can you confirm that the geometry is represented as "the_geom" as you expect?

Is the service available at all? If not please attach the capabilities document and the describe feature type result. We don't really have enough to go on with the stack trace you provided.

Ok, I did a DescribeFeatureType request and found out that our self-made proxy (around Geoserver) dosen't convert the references to the xsd documents. Apparently uDIG 1.1.x didn't have problems with this omission, so it wasn't until we installed version 1.2 before we faced this issue.

Anyway, you can close the ticket, we'll have to fix this ourselves ;-)
