Hi,
I'm experiencing a problem given the constellation mentioned above.
In one of my entity classes I've got a method like this:
| public AbstractKonsiliarbogen createModelInstance() {
| AbstractKonsiliarbogen instance = Utils.konsiliarbogenModelInstance(getName());
| instance.setKonsiliarbogenZuVertrag(this);
| return instance;
| }
|
the konsiliarbogenModelInstance() method will just use Class.forName to instantiate a
certain model instance.
In one of my server tests where such an instance is returned to the
remote client (using serialization) I get an exception:

When I omit the call to instance.setKonsiliarbogenZuVertrag(this)
it works. Funny though that the method called is called from within
javassist itself according to the stack trace.
Cheers
