Hi,

I am having problem to query on a persistent class using as a parameter an object that has a composite key. It seems that the problem is the way the oracle sql is created. Unfortunately we cannot avoid having composite keys. Four classes are involved in the example below, 3 of them are persistent and the fourth is an Id class for the composite key.
