-----------------------------------
Resolution: Invalid
Assignee: Igor Vaynberg
this has already been fixed in 1.4rc2, your quickstart is against rc1
> Temporary behaviors break behavior id:s
> ---------------------------------------

> Key: WICKET-2141
> URL: https://issues.apache.org/jira/browse/WICKET-2141
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4-RC2
> Reporter: Martin Makundi
> Assignee: Igor Vaynberg
> Priority: Minor
> Attachments: Wicket-Quickstart.zip
>
> Original Estimate: 5h
> Remaining Estimate: 5h
>
> Temporary behaviors break behavior id:s:
> component.add(temporarybehavior);
> component.add(permanentbehavior);
> results in: java.lang.IllegalStateException: No behavior listener found with
> behaviorId 1; Component: [MarkupContainer [Component id = ajaxUpdate]]
> at
> org.apache.wicket.request.target.component.listener.BehaviorRequestTarget.processEvents(BehaviorRequestTarget.java:95)
> at
> org.apache.wicket.request.AbstractRequestCycleProcessor.processEvents(AbstractRequestCycleProcessor.java:91)
> at
> org.apache.wicket.RequestCycle.processEventsAndRespond(RequestCycle.java:1188)
> at org.apache.wicket.RequestCycle.step(RequestCycle.java:1265)
> Reason: The behaviors are named according to their indexes. When the
> temporary behavior is detached, the permanent behavior's id points to index 1
> which does not exist anymore.
> Workaround:
> always add your temporary behaviors LAST so they will not affect the
> permanent behaviors' indexes.
> What is really strange:
> The WicketTester JUnit test works with no problems, but if you try the
> attached quickstart with your browser, the textfield onblur event crashes.
