Cause
This error occurs if there is an attempt to update an automatic reference from user code.
Inverse references can be defined as having a manual reference at one end and an automatic reference at the other. Manual references can be updated by user code, and the automatic reference is updated automatically by the JADE Object Manager in response to this. You cannot attempt to update an automatic reference from user code.
Action
Remove the invalid assignment. You can update the manual end of the inverse instead, which causes the automatic reference to be updated automatically.
