[udig-devel] change new feature

[Jesse Eichar]

Wait a minute....  You're on Trunk...  Wow brave man :).  I completely  
missed that until now.  You probably know by now but Geotools trunk  
(and therefore uDig trunk) have gone through some major change with  
regards to filters and features.  So I'm not surprised there are bugs.

I'm having problems reproducing the issue.  I'm working on a  
Shapefile, so maybe that is my problem.  I've attached a plugin with 2  
operations the first adds a couple of features via the  
AddFeatureCommand.  and the second is called modify and it prints out  
what it gets from the AddFeaturecommand.getNewFeature.  It is really  
stupid code but it is my understanding of what you are reporting.  If  
you can try it out or maybe change it so it produces your bug I'd  
really appreciate it.
