Craig Russell reassigned JDO-390:
---------------------------------
Assignee: Michelle Caisse (was: Andy Jefferson)
Andy is right. The test doesn't actually test what it's supposed to. Instead of
comp.setFounded(testDate);
it should be something like
testDate.setTime(123789L);
And then the tests should make sure that the company instance in memory is not
dirty (test is ok here) and that the instance in the database still has the
same Date as it did earlier, using an equals test.
There is a pretty good summary of the issue at
http://mail-archives.apache.org/mod_mbox/db-jdo-dev/200606.mbox/[EMAIL
PROTECTED]
The consensus is that if you project a Date from a query, the Date you get is
not an owned SCO. It can be an SCO if your implementation chooses (the only
requirement is that it is assignable to Date) but it cannot be owned.
The test method projects a Date, modifies it, and then verifies both that the
instance in memory whence the projected Date was obtained is not modified, and
that the instance in the database is not modified.
> JPOX fails new test: change to projected Date field is reflected in the
> database
