    [ https://issues.jboss.org/browse/RF-11054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12644058#comment-12644058 ] 

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

This code does not trigger the NPE - This is the close button on the tab. But the tab must be selected for working.

<rich:tab id="#{tab.id}" name="#{tab.id}" actionListener="#{desktopTabController.tabListener}">
<f:facet name="header">
   <h:panelGrid columns="2">
   <h:outputText value="#{tab.id}" />
   <h:commandButton image="/images/closeButton.png"
               styleClass="closeButton"
                  action="#{desktopTabController.closeTab(tab.id)}" />
  </h:panelGrid>


This code triggers the NPE - This code follow the sample of : http://livedemo.exadel.com/richfaces-demo/richfaces/tabPanel.jsf?tab=delete&cid=420041

<h:graphicImage value="/images/closeButton.png"
	   styleClass="closeButton"
	      onclick="closeTab('#{tab.id}');Event.stop(event);"
	    immediate="true" />

<a4j:jsFunction id="closeTab" name="closeTab" action="#{desktopTabController.closeTab}" render="desktopTabPanel">
<a4j:param name="tabId" assignTo="#{desktopTabController.closeTabId}" />
</a4j:jsFunction>
