Subject Re: Problems using select in select to exclude results
Date Fri, 17 Jul 2009 12:04:18 GMT
Hi Ulf,

This is a bug. Some of these bugs have been addressed in
OPENJPA-681<http://issues.apache.org/jira/browse/OPENJPA-681>(fixed in
1.2.1) but there are some that still exist.

Catalina & Fay (on the dev team) have done a lot of work to improve how
OpenJPA handles subqueries. I'm taking a look at their approach now and
seeing whether it can be merged into earlier releases (like 1.2.2).

Could you try running with 1.2.1 and see that helps? If you're hitting a
scenario that isn't covered by OPENJPA-681 that would be a good data point
for determining whether we need to merge Catalina & Fay's changes.

Hope this helps,
-mike
