| reloading genmodel fails [message #398573] |

Hi all,
I'm just running into a strange problem.
When I try to reload some genmodel, it fails to detect the available
ecore models (I'm generating from annotated java code). I can see an
NullPointerException in the log (stack trace included at the end for
plugin org.eclipse.emf.importer.java).
But, if I just cut & paste the project (with a different name) it works
just fine... So I suspect some configuration files to be corrupted?
Unfortunately I cannot find something like that in the Eclipse's
metadata folder.
Any clue?
Serge.

Thanks Ed...
Actually I just upgraded EMF to the last release and now it works nice :)
Regarding your questions:
- I can open the .genmodel
- I cannot create a new one
Cheers,
Serge.
