[richfaces-issues] [JBoss JIRA] (RF-11054) Dynamically created tabs within tabPanel causes NPE in getActiveItem()

[Jean ANDRE (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/RF-11054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12644049#comment-12644049 ] 

Jean ANDRE commented on RF-11054:
---------------------------------

There is definitively a link with the component outputPanel. When the outputPanel is removed, the exception may not appear. Removing the tab, by the onclick on a graphicImage has not the same effect as using the h:commandButton with action. In the second way, it does not trigger the NPE but the tag must be selected before to be able to delete the tab.

Moreover, I've just try the version 4.1.0 M4, this version displays the following stack trace instead of the NPE - We do not have a NPE but an IndexOutBounds Exception. Setting the activeItem, was ever the way (binding, activeItem, by ViewRoot.findComponent,...), does not have any effect.


Here is the stack trace.
