Hello,

I have a class called 'Flow' extends two classes 'DirectedElement' and 'Property'. I have one more class called 'PropertyContainer' which contains 'Properties'(Containement=true). I am able to persist PropertyContainer using TENEO and Hibernate. But when i tried to retrieve , getting the following exception

com.test.DataManagementException: Object with id: 275 was not of the specified subclass: Property (Discriminator: Flow)

DB has row with ID '275' pointing to 'Flow' dtype.
Please let me know how to address this issue.

Thanks
Chandru

Hi Chandre,
Multiple inheritance is not handled completely in ORM's:
