     [ https://issues.apache.org/jira/browse/CAY-1751?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrus Adamchik closed CAY-1751.
--------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 3.1 (final))
                       (was: 3.0.2)

Closing this, as we have a workaround. Going forward we may need to improve "native" handling to value propagation across relationships between non-pk columns
