Subject [jira] Commented: (OPENJPA-1280) OneToMany Bidirectional inverse relation not set when using data cache, fetch groups
Date Tue, 01 Sep 2009 22:45:32 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12750165#action_12750165

David Minor commented on OPENJPA-1280:
--------------------------------------

I didn't come up with a good fix for this, but as noted in the mailing list, reverting the
changes for OPENJPA-744 fixed this issue.

> If there is an instance of the other side of a OneToMany bidirectional relation in the
data cache, and it was not fetched with the bidirectional relationship set (i.e., turned off
in a fetch group), the inverse relation will remain null even when the "One" side is fetched
normally.
