Subject [jira] Commented: (CAY-1520) Deleting Objects with Flattened Read-Only Relationships
Date Mon, 06 Dec 2010 11:54:11 GMT

    [ https://issues.apache.org/jira/browse/CAY-1520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12967160#action_12967160

Andrus Adamchik commented on CAY-1520:
--------------------------------------

Good to know that you found a workaround. Runtime relationships (those relationships created
implicitly by Cayenne to avoid forcing users to create them), are causing quite a bit of trouble
in a number of mapping scenarios. So here we have another one.
