[mapguide-users] MG 2.0 RC4 selection ALMOST working

Ok, I found Jason's problem but it was in code that is not in the  
general release so I don't know where the other problem is coming from  
even though it has the same exception.  In Jason's case, there was a  
layer being programmatically created that had an incorrect property  
mapping (it referred to a field in the feature source that didn't  
exist).

Is it possible to get an mpg of your map/layer/data or a subset enough  
to reproduce the problem?  You can send directly to me.

Cheers

Paul
