[jira] Resolved: (ODE-531) Failing copy from xquery query leads to
failing whole job
[ https://issues.apache.org/jira/browse/ODE-531?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Karthick Sankarachary resolved ODE-531.
---------------------------------------
Resolution: Fixed
Thanks to Rafal for identifying and resolving this issue with query evaluation that had gone undetected for way too long. Thanks to Mark for identifying the right type of standard fault to throw in this particular case (I too believe that the root cause of the problem qualifies as an "unhandled fault" as opposed to an "inability to select nodes".) The revised patch has been applied at revision 748707.
I guess that "neat little trick" in the ASSIGN activity wasn't so neat after all :-)

> Instead, there ought to be 'selectionFailure' fault raised.
