Hello,

i want to add some elements to a cdoresource. So i take a CDOResource
CDOResource resource = transaction.getOrCreateResource(res+i) and add
some elements resource.getContents().add(obj). These Objects are created
by the normal xYzFactory . If i commit now, i get an exception that some
objects has no resource. Is it not possible to add generated Objects
to an CDOResource? What resource do they need so i didn't get this
exception?

Greetings
Jörg

You have probably a dangling reference problem.

For each object you add (in your example "obj") You need to check
EReference that containment = false. If this is the case you need to
make sure these objects belong to a resource.
