All,
As the maillist is out of order, I would like to know if there are some
trouble with the dynamic proxy ?
I have two objects A, B who work fine with Ojb and since I have been puting
the "dynamic" proxy in the repository.xml it haven't been working.
I only do this :
Object A implement InterfaceA
Object B implement InterfaceB
proxy="dynamic" in the repository.xml
Declaration of the InterfaceA and InterfaceB with all the method signatures
of A and B.
That's all.. This is driving me nuts !!
I have some collections between A, B and C, D..
It fails at the attributes b from A with is a link to B.
