Hi,
I made an ecore model where a class has an attribute defined as a list of EEnum values. When reading the attribute's value, a ClassCastException occurs with the following message :
Quote:An error has occurred. See error log for more details.
org.eclipse.emf.cdo.internal.common.revision.CDOListImpl cannot be cast to java.lang.Integer
To reproduce the problem, open a CDO Session in Eclipse and register the attached test.ecore file. Open a transaction, create a resource then create a new root of type "Sample object". Then, open the properties of the created instance, edit the "Sample attribute" and press OK to see the error message.
I use CDO 3. In my opinion it looks like a missing feature in CDO. Is there a workaround for it ? Maybe it is implemented in a more recent release ?
The stack trace is :

Hi Julien,
I just tried it with the current HEAD revision of CDO and there it
works. So, I guess your issue is really a missing feature/a bug which
has been fixed in the meantime.
Cheers

Hi Julien,
Please also note that CDO 4.0 will be generally available (GA) next month.
