[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2916) Unsupported Operation Exception crash due to (invalid) multi-restriction

[Wolfgang Laun (JIRA)]

    [ https://issues.jboss.org/browse/JBRULES-2916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12594948#comment-12594948 ] 

Wolfgang Laun commented on JBRULES-2916:
----------------------------------------

This seems to be gone, although the reported rule code now causes the problem reported in JbRULES-2951.

This compiles OK
   Assignment( $target: target == ($a.getSource()) || == source )
