(hibernate 3.1 12.12.2006)

I use inheritance as described in the "Table per class hierarchy".

I have AbstractA mapped to TableA, currently with one descriminator to ConcreteA

I have AbstractB mapped to TableB, currently with one descriminator to ConcreteB

in AbstractB i have a collection mapping to AbstractA -

when using
Code:
for (ConcreteA  a : concreteB.getAList() )


I get a
Code:
classCastException :
AbstractA$$EnhancerByCGLIB$$896e75b6


so apparently, hibernate reads into the collection AbstractA instead of ConcreteA !
-

the discrimintor value is set in the row, so hibernate must be skipping inheritance when mapping to a collection ?

Thanx in advance,
Ron
