Description

In cases of inheritance non-leaf entities may have synthetic qualifiers that mention the same attribute more than once. E.g. personType = 'EE' or personType = 'EM'. When Cayenne compiles a descriptor, it ends up with 2 instances of ObjAttribute for personeType. This seems benign, still it is incorrect.
