------------------------------------
Jean ANDRE,
I would first like to thank you for the time you spend submitting these bug reports to
help improve the project as a whole. However, I would like to put the onus on you to help
us identify the specifics of a problem, before you file an issue.
A simple approach to take, is to make a copy of your application, and start trimming away
features and libraries to isolate the problem involved. You know your application far
better than we, and are in a much better position to start paring the cruft away.
Once you have the simplest possible scenario (both in terms of features, and required
libraries) that demonstrates the problem, then submit it to us in an issue report.
The Richfaces project is not alone in asking for such [Short, Self Contained,
Correct|http://sscce.org/] (and I'll add Runnable!) Examples. Such an effort on your
part can only serve to streamline the resolution of the underlying problem.
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
Attachments: index.xhtml, listClient.xhtml, ResultClientController.java,
searchClient.xhtml, SearchClientController.java, tabsClient.xhtml,
TabsClientController.java
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">
 
</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>
{code}

Please, not that the application is a single page application, everything appends inside
a single page. Dynamic include is used to achieve this goal (see index.xhtml) - Tab is
also dynamic except for the search. See screen shot.
