             Summary: RichFaces Showcase portlet is unable to switch skins
                 Key: AS7-5970
                 URL: https://issues.jboss.org/browse/AS7-5970
             Project: Application Server 7
          Issue Type: Bug
          Components: JSF
    Affects Versions: 7.1.3.Final (EAP)
            Reporter: Ken Finnigan
            Assignee: Stan Silvert


The following exception is thrown when the user changes skins for the second time immediately after changing the skin for the first time:
{noformat}
Caused by: javax.faces.FacesException: Cannot remove the same component twice: pbG9dea276d_2dee9e_2d4150_2dad91_2d22255b5a57d2_j_id1:j_idt444

This error manifests due to the Portlet Bridge needing to retain the UIViewRoot from JSF between Portlet Requests, which causes the list of component tree actions, ie. adding and removing, to be retained making JSF think that it's trying to remove a component that was actually removed in a previous request.

This has been raised as http://java.net/jira/browse/JAVASERVERFACES-2609, but wanted to raise this as a tracker so that when that fix is available it can be incorporated.
