Jean ANDRE commented on RF-11985:
---------------------------------

Hello Brian,

Well, agree with your request - We understand your needs. For this bug, we have cancelled the migration to MyFaces/CDI because under WAS we are not able to upgrade to the latest version of 2.1.6. We learnt that WAS 8 is using MyFaces 2.0.2.... We got also some other problems as explained below:

After we changed the code to use the c:if and the subView (see forum: https://community.jboss.org/message/721147), the modifications made to the code does not allow the application to perform well under MyFaces. We got some error messages about duplicate Ids even if the application does not have any duplicate Ids and even if the application is running perfectly under Mojarra. Another problem we found is about the id syntax. Under RAD/MyFaces, having an id like #{tab.id}-blabla is not correct but with Mojarra, it is. We absolutely need to have a calculated Id as we create dynamically some tabs and as we include several occurrences of the same physical fragment.

Actually, the status is: under Mojorra, the application performs well. Under MyFaces 2.0.2 the application is not compatible. (sounds strange...)

If time permit, we will try to test the application under another application server with the latest implementation of MyFaces and with the latest implementation of CDI (OWB). I will return back to you if we got some interesting results for you.

Sincerely - Jean.

> 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.
