I have created an EMF project that was working ok using Eclipse 3.1, newest MyEclipseIde (4.0GA), and the patched/latest EMF (2.1.1 Milestone of 8/15/05).
I get the following error when I first try to create a UML diagram.
It appears to go away after I do reverse engineering of the generated interfaces.
Until then, it was happening frequently.BTW: reverse engineering of the EMF generated code is not particularly useful.
java.lang.NullPointerException
