Hi,

I have a problem:

In our project we use self-referencing for storing orders and the dependend suborders in the same table. With this organization it is possible to create an order-tree of dependend orders.

If you place an a self reference in the cayenne modeller there is no possibilty to set the reverse relation, and without reverse relation, cayenne doesn't work right now.

I know that this mechanism is good for having no endless loops when populating a data object.

So what can I do. The database structure is given, because I'm working on an existing database coming from our base product. So there can be made no changes.

Juergen
