Cloning Calendar proxies doesn't detach from StateManager
---------------------------------------------------------
Key: OPENJPA-396
URL: https://issues.apache.org/jira/browse/OPENJPA-396
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 1.0.0, 1.0.1, 1.1.0
Reporter: Kevin Sutter
Assignee: Kevin Sutter
Fix For: 1.0.1, 1.1.0
This problem was first discussed on our dev mailing list:
http://www.nabble.com/Cloning-Calendar-proxies-tf4571181.html
Per the discussion on that thread, I am proposing to modify the generated proxy
code to override the clone() method. This clone() method will do the necessary
copying of data from the original object, but then also null out the sm
(StateManager) and zero out the field attributes. This action detaches the
cloned object from the StateManager (and associated EntityManager).
Instead of limiting this action to the Calendar proxy, I am adding the clone()
method implementation to all of our proxy objects that we generate. Granted,
some of the object types do not directly support the clone() method, but that
will be detected when or if anybody attempts to use the clone() method on these
types (compiler generated error message).
I'll be posting a patch shortly and I plan to commit the changes later today
(unless there is opposition).
Thanks,
Kevin
