[Dan Berindei (Jira)]

    [ https://issues.jboss.org/browse/ISPN-3643?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13711972#comment-13711972 ] 

Dan Berindei commented on ISPN-3643:
------------------------------------

The behaviour was already implemented, see {{ListenerExceptionTest}}.

I don't believe listeners are the best way to do validation though, because the listeners run both on the originator and on *all* the owners. In addition to doing more work, if the cache is transactional with 1PC or non-transactional, if the listener throws an exception on one of the owners will veto the change only on that owner.

> Two ways of doing this:
> - listener throws an exception
> - add an Event.abortTransaction()or Event.veto(false) on the listeners.
