Description Alex Lagarde CLA 2010-11-09 05:29:26 EST 
Build Identifier: 20100917-0705

The clearList() method of CDOLegacyWrapper casts each list item in InternalEObject. This can cause a ClassCast Exception, especially with enumerations (if the item implements Enumerator for example). 

By simply removing this cast, the problem don't occur and lists are correctly cleared.


Reproducible: Always

Patch v1

I attached the fix. Since our test models do not have many references with enumerations I was not able to test it yet. 

I will change this soon...

Test v1

I tweaked test model 2 a bit to make the problem reproducible. Now we are able to validate the patch.
