    Optional to-one are totally ok. Cayenne handles most of them well, as
    long as "to Dep PK" is checked for one of the sides of DbRelationship.
    If "to Dep PK" doesn't fix the problem, I still urge you to open a bug
    report. Catching an exception is a good workaround, but we can do
    better. Make sure you attach your DataMap file to the report.

    Thanks
