The following solved my problem: request = AppManager.getRequestFactory().personRequest(); *object = request.edit(object);* //object is the Proxy passed to me // *request.edit(object);* // instead of this...
Actually edit(object) returns a new "mutable version" of the entityProxy, that can be worked with. Changing values and persisting did not cause exceptions anymore. Am Montag, 24.
