    [ https://issues.jboss.org/browse/RF-12026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678870#comment-12678870 ]

----------------------------------

Brian:
Yes, here is a small sample that will reproduce the error: It displays an ExtendedDataTable with the clientRows property set. If you drag the vertical scroller to the bottom, the table wount render anything due to the js-error.
Browser: FireFox 3.6.28

A fix would be to replace the guard "if (event) {" with "if (event && event instanceof Object) {" (line 129 in richfaces-queue.js).
