expanding a panelMenuGroup in panelMenu (inside dataGrid)

[upstream]

Hi,
I am trying to display a panelMenuGroup inside a dataGrid as an expanded group upcon rendering. However, I am failing. My code looks similar to the below, but I am unable to have my groups appear expanded. Anyone with input on what I am doing wrong (and how to make it right)?

<rich:dataGrid id="id" rowKeyVar="rowkey" var="group" columns="1" elements="#{object.items.size}" value="#{object.items}">

 <rich:panelMenu id="panelMenu"
 iconExpandedGroup="disc" iconCollapsedGroup="disc"
 iconExpandedTopGroup="chevronUp" iconGroupTopPosition="left"
 iconCollapsedTopGroup="chevronDown" >

 <rich:panelMenuGroup expanded="true" label="#{group.name}" >

 <rich:panelMenuItem action="#{panelMenu.updateCurrent}" >

 <s:div> various stuff... and then closing tags

Thanks for any advice!

which RF version used?

I a, embarrassed to say I dont know :S
It is part of my JBoss Developer Studio - where I have the 2.0 version I believe (build id: R200903141247-H4, build date: 200903141316). With that I installed jboss-seam-2.1.1.GA . I believe it is the JBoss enterprise application server with that, version 4.3 - if that gives any more information.

On second thought, I am assuming it is version 3.3.0. as I installed it in April of this year. i see a new version came out in May.

try to update RF to latest 3.3.1GA or 3.3.2 SNAPSHOT.

Thank you :)
Is there a URL that I can use with EClipse/JBoss Dev. Studio for that, or do I need to download manually? (I am a bit of a newbie, so feeling less confident about the latter and how to go about it).

I downloaded the tar-file and copied the jar-files into my application's lib/ folder (substituted the old richfaces jar-files). I then cleaned and recompiled my application, but the expanded view is still not working :S I am a bit clueless to where I may have done something wrong.

Not sure if it can make a difference, but I have the panelMenu mode attribute set to "none", and also tried "ajax" (don't want to use "server" as it interferes with some buttons I am using in my items).
