ExtendedDataTable reRendered even if out a4j:region with renderRegionOnly=true
------------------------------------------------------------------------------

                 Key: RF-6482
                 URL: https://jira.jboss.org/jira/browse/RF-6482
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.3.0
         Environment: Windows XP PRO SP2
Glassfish V2 UR2
JSF 1.2_09

JSP, Not using Facelets
Affects: FF and IE
            Reporter: Nicolas Gaudin


Hi all,

I have several a4j:include all in one page :
 - TREE: one for a tree of folders (not system folders, but categories of items) 
 - EDT: one for a list of items belonging to a particular category (the EDT)
 - ITEM: one containing the detail of each item (rerendered when clicking on a row of the EDT)

so when clicking on a treeNode of TREE, the list of items is reRendered via a4j:support  with reRender="dataTable" : this is working OK

BUT,  when I do operation on the tree (ex:DnD, deletion of a node via contextmenu, etc...each time an ajax request is sent (via a4j:support mainly), EDT is reRendered in BACKEND.
I mean by "backend" that it is not visual on the UI but I see it occurs in my log. 
This impacts a lot the performance of my application.

ALSO, when user changes the details of a selected item (ITEM include) and use a suggestionbox (for instance), again i see in the log that the EDT is Rerendered.

ITEM include  (not like the TREE that needs to actually rerender the EDT or the EDT  that needs to actually rerender the ITEM) has nothing to do (no rerender interaction) with the TREE or the EDT.
So, I tried to encapsulate ITEM include in a4j:region with attribute renderRegionOnly set to TRUE.
Nothing seems to work..

This only thing i can say is that it has perhaps something to do with EDT tablestate???? because i see it in the log (having logged getTableState in managed bean) at the beginning AND at the end of this weird rerendering thing

Do you have any idea on this, any quick workaround?

 Many thanks in advance for your answers
Nicog
