Exception removing an attribute
-------------------------------

                 Key: CAY-1406
                 URL: https://issues.apache.org/jira/browse/CAY-1406
             Project: Cayenne
          Issue Type: Bug
          Components: Modeler
    Affects Versions: 3.0RC2
         Environment: Windows 2000 P., JRE 6
            Reporter: Oscar Maire-Richard


I created a DBEntity, then the Object, and a untitledAttr appeared (I didn't create it consciously).
When I tried to remove the attribute an exception was launched:
