Thanks for the word of warning.  I'm by passing the EMF2SSEDOM framework 
all together, so I shouldn't run into that issue.  I need to redo the 
Undo and Redo functionality anyways for VEX as it's not currently 
implementing the existing Eclipse functionality, it has it's own.  So 
lots of little restructuring to do over the coming months.
