             Summary: element is null message when closing tab from an event click
                 Key: RF-12060
                 URL: https://issues.jboss.org/browse/RF-12060
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.2.0.Final
         Environment: Websphere 8.0.0.2 - RAD 8 - JSF Mojorra 2.1.6 - Spring 3.0.6 Final - Firefox 10.0.2 - Windows 7 (6.1 sp1) - AspectJ 1.6.12 / AJDT - RichFaces 4.2.0 Final - Hibernate Validator 4.2.0 Final 
            Reporter: Jean ANDRE


There is a link to RF-11950.

We got the message "element is null" when we send a click event for closing a tab. To retrieve the id of the close button (an image), we use the function getElementById (because of RF-11950). The click function calls a javascript function declared by a4j:jsFunction (see index.hxtml file - close task).

This is the only information we have from firebug. When we close the tab directly by clicking on the close button/image, it works perfectly.

*Note :* Moreover, there is also a strange behavior related to generated id on close button/image. When we specified a fix id on the h:graphicImage, the first id is correct but there is no id on other close button/image from other tabs!???. Having a fix id should trigger a duplicate ID but as the ids are not generated on other tabs, it does not.

{code}
<f:facet name="header">
   &#160;<h:outputText value="#{msg[task.uiActivity.headerKey]}"
                       title="#{msg[task.uiActivity.headerKey]}" />
    &#160;<h:graphicImage id="closeTask" value="/images/closeButton.png"
                  styleClass="closeButton"
                     onclick="closeTask('#{task.id}');event.stopPropagation();" />
</f:facet>
<f:subview id="#{task.id}-subview">
   <ui:include src="#{task.uiActivity.xhtmlFile}" />
</f:subview>
{code}
