Subject [jira] Commented: (CAY-1379) Error resolving fault, no matching row exists in the database
Date Wed, 27 Jan 2010 16:14:34 GMT

    [ https://issues.apache.org/jira/browse/CAY-1379?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12805558#action_12805558
] 

Victor Antonovich commented on CAY-1379:
----------------------------------------

Looks like Cayenne incorrectly resolve faults under some conditions. In attached testcase
dataobjects in inheritance tree (Roles/Users/Groups) are linked to groups by flattened relationships.
At some moment (after performing SelectQuery, see testcase) modified but uncommitted DataObject
change initial null values of to-one relationships to nonexistent (hollow?) objects. Trying
to delete those objects causes error.
