Subject [jira] Commented: (JDO-522) Draft proposal for CopyOnAttach property
Date Wed, 19 Sep 2007 22:43:12 GMT

    [ https://issues.apache.org/jira/browse/JDO-522?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12528946

Craig Russell commented on JDO-522:

Thanks for the image of the life cycle transitions. When I turn this into Frame, I'll note
that the state transitions for makePersistent is with the CopyOnAttach flag false and for
commit is with DetachAllOnCommit true. Don't bother updating the image; I can't just copy
it anyway.
