Doc Text:	JSF Component events were being retained between an Action and a Render of the portlet on the UIViewRoot. Removing or adding JSF components in the page was occurring twice, which caused exceptions about components no longer being present or already added. The JSF Mojarra implementation is now updated to remove events that may be present when setting a UIViewRoot directly onto the FacesContext, as is the case with PortletBridge. Exceptions about components being removed or added too many times no longer occur, and the page now behaves as expected.	Story Points:	---

Description Ken Finnigan 2012-11-16 21:27:56 UTC

Following exception is seen when changing skins for the second time immediately after the first:


Caused by: javax.faces.FacesException: Cannot remove the same component twice: pbG9dea276d_2dee9e_2d4150_2dad91_2d22255b5a57d2_j_id1:j_idt444
	at com.sun.faces.context.StateContext$AddRemoveListener.handleAddRemoveWithAutoPrune(StateContext.java:489) [jsf-impl-2.1.13-redhat-1.jar:2.1.13-redhat-1]
	at com.sun.faces.context.StateContext$AddRemoveListener.handleRemove(StateContext.java:371) [jsf-impl-2.1.13-redhat-1.jar:2.1.13-redhat-1]
	at com.sun.faces.context.StateContext$AddRemoveListener.processEvent(StateContext.java:334) [jsf-impl-2.1.13-redhat-1.jar:2.1.13-redhat-1]
	at javax.faces.event.SystemEvent.processListener(SystemEvent.java:106) [jboss-jsf-api_2.1_spec-2.0.7.Final-redhat-1.jar:2.0.7.Final-redhat-1]

Investigating this problem lead to determining that it was caused by the need for Portlet Bridge to retain the UIViewRoot from JSF between requests, and the list of ADDED/REMOVED components being retained between requests, making JSF believe it was removing a component for the second time when it fact it wasn't.

This has been raised as http://java.net/jira/browse/JAVASERVERFACES-2609 against the Mojarra JSF implementation.

There is also a tracker on AS7 jira to have the fix added when it's available: https://issues.jboss.org/browse/AS7-5970

So to make it clear there is nothing we can do with this issue at this point - until it gets fixed in EAP. 

This may need to be postponed after JPP 6

Are you guys satisfied that this is fixed now that JAVASERVERFACES-2609 is done?  Upstream fix should be integrated now.  Can we close this?

I don't see a problem with that. Safe to close from my perspective

Comment 5 Boleslaw Dawidowicz 2013-04-17 07:58:53 UTC
