Andi Huber commented on ISIS-1963:
----------------------------------
This might be related to an earlier discovery by [~danhaywood] [1] finding that
the actual page object gets replaced in the background, during an AJAX request
response cycle, which causes similar issues, where we simply ignore the errors
as reported by Wicket (XmlPartialPageUpdate warnings) on our side.
