> 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.

> 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.
