Hi,
I try to create an EMF project with this Ecore metamodel.

the problem comes when i need to choose the root package. I can only
select the first one. If i select the second one, an error occurs. The
logs are below :
!ENTRY org.eclipse.jface 4 2 2006-12-27 10:37:02.266
!MESSAGE Problems occurred when invoking code from plug-in:

...
If I only select the first package, the project is generated but in the
genmodel file, there is only the first package.
I have tested with Eclipse 3.2.1 and EMF 2.2.1.
