Exception when importing an EOModel with single table inheritance
-----------------------------------------------------------------

                 Key: CAY-764
                 URL: https://issues.apache.org/cayenne/browse/CAY-764
             Project: Cayenne
          Issue Type: Bug
          Components: CayenneModeler GUI
    Affects Versions: 2.0 [STABLE]
            Reporter: Simon
         Assigned To: Andrus Adamchik

I'm trying to import an EOModel with cayenne Modeler and i'm getting the exception pasted below. ABSTRACT_FOP is a table that has a super entity and 2 sub entities mapped to it.

Is it not possible to import an EOModel that has single-table inheritance ?

Thanks, Simon
