    Thanks for the reminder. I thought this problem sounded familiar.

    Take a look at this from Cayenne Release Notes 1.1 B2:

    > - DataObject.resolveFault() will now throw an exception if the underlying
    DB row does not exist

    According to this, 1.1B2 started throwing Exceptions in addition to marking
    the object transient.

    Also covered in
    http://objectstyle.org/jira/secure/ViewIssue.jspa?key=CAY-132, so you may
    want to vote for this issue if it's important to you and you don't like the
    workaround.

    Sounds like it's a bug that'll be fixed after 1.1 (so that null is returned
    instead).
