WFS and uDIG IllegalArgumentException

Tue Aug 8 19:39:47 EDT 2006

We've been doing WFS cleanups for the last while, and have fixed a large 
number of issues, and also found others:

- Our WFS support is much stronger in the ongoing 1.1RC series than in 1.0
- The Mapserver WFS support does some illegal things in versions prior 
to 4.8, which makes support spotty for ealier versions (some feature 
types work, others don't, some things work depending on the kind of 
backend you have, others don't, etc).

The sad truth about WFS so far is that it seems to be quite hard for WFS 
servers to obey the schema/instance contract... they advertise different 
things in the DescribeFeatureType schema than they actually provide in 
the GetFeature instance.  We have been turning these kinds of things up 
in commercial WFS servers too -- a complex specification takes no prisoners.
