Hi,
We are developing a tool for creating diagrams. We have the need to create Shortcuts and integrated the Dawn code into our latest editor code.
When a Shortcut is created, seems like the EAnnotation cannot be saved in CDO. This used to work when we were handling xml files.
The stack error is:
java.lang.NullPointerException

We noticed that any other object has an attribute (visible when debugging) that seems the responsible of saving it. In case of the EAnnotation "shortcut" seems like these attributes are not populated.
Hope we can fix this because CDO (and Dawn) is incredible. Thanks in advanced!

I've cc'ed Martin for Dawn and CDO Legacy Mode questions. I'm sure we can sort this out. I guess Martin will need an ecore file from you that can reproduce the issue. Please submit a bugzilla and attach it there. Also mention the exact version you're using.
