Hi Team,

we developed the .diagram files from EMF eCore functionality with org.eclipse.emf.transaction management functionality.

We unable to save the .diagram files in Compare API using the merge functionality.

We are getting the below Exception

You also opened this:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=549563

You seems to have something special installed, com.intervoice.gtf.compare, so it's hard to comment on what that might be doing.
