Teresa Kan updated OPENJPA-370:
-------------------------------
Attachment: TestFetchGroup.patch
I modified the TestFetchGroup testcase based on the current discussion and
understanding of the fetch group and loadFetchGroup concept.. The testcases
work with the current implementation now. However, I have one question about
Craig's comment on the testcase 002,
Craig said,
"The difference between test001 and test002 isn't checked. In test001, lastName
and firstName should be not null because they are in the default fetch group.
In test002, they should be null because the reset fetch group has no fields."
According to the documentation, resetFetchGroup will reset back to the global
configuration which I interpreted it as the default fetch group plus the
property defined in the persistence.xml file . That's how the current
implementaiton work at this moment. Therefore, both firstName and lastName are
still available (not null) even though resetFetchGroup has been called.
Please confirm the interpretation! If this is not true, then we have a bug in
the openjpa for the resetFetchGroup.
Thanks
