             Summary: rich:dataTable with MyFaces 2.x.x - Target Unreachable, identifier 'client' resolved to null
                 Key: RF-11985
                 URL: https://issues.jboss.org/browse/RF-11985
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.2.0.CR1
         Environment: MyFaces 2.0.x and 2.1.6 - RichFaces 4.2.0 CR1 - WAS 8.0.0.1 - Spring 3.0.6 - Hibernate Validator 4.2.0 Final
            Reporter: Jean ANDRE
            Priority: Critical


We made a test under MyFaces implementation of JSF 2.0 and actually we got an error with the dataTable. At the first call of the web page, the dataTable performs well but once the dataTable is redisplayed, the dataTable is unable to reach an existing variable declared by the attribute var (ex.var="client").

We made also the test by using the h:dataTable, the standard JSF tag and it is working perfectly - As you know we also use Mojarra as JSF implementation and it's working too. Then the problem seems to come from with rich:dataTable. Nothing very special here in using the tag.

{code}
		<rich:dataTable id="resultListClient" var="client" value="#{tab.searchResult.data}" rendered="#{not tab.searchResult.isEmpty}" row="30" rowClasses="odd-row, even-row">
			<rich:column id="dejaVu" rendered="#{not resultClientController.isEmptyDejaVu()}">
				<!--            -->
				<!--  DEJA VU   -->
				<!--            -->
				<f:facet name="header">
					&#160;
				</f:facet>
				<h:graphicImage value="/images/checked.png"
							 rendered="#{resultClientController.isDejaVu(client.id)}"
							 alt="#{msg['common.dejaVu.alt']}"
							 title="#{msg['common.dejaVu.tooltip']}" />
			</rich:column>
