             Summary: NullPointerException in DbEntityTabbedView.stateChanged(DbEntityTabbedView.java:95)
                 Key: CAY-1787
                 URL: https://issues.apache.org/jira/browse/CAY-1787
             Project: Cayenne
          Issue Type: Bug
          Components: Modeler
    Affects Versions: 3.1B1
         Environment: OS X 10.8, CM 3.2M1-SNAPSHOT, Build Date: Dec 18 2012 09:51:56
            Reporter: Andrus Adamchik
             Fix For: 3.1B2, 3.2M1
