-------------------------------
Summary: element is null message when closing tab from an event

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">
 <h:outputText value="#{msg[task.uiActivity.headerKey]}"
title="#{msg[task.uiActivity.headerKey]}" />
 <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}
