XML form field choice list to be populated by collaboration room names

Question

I would like to create a news form used within collaboration rooms where one field should include the name of the room where the news entry is created.
Preferably this should be done automatically as works for date and author fields ($date, $sap_user), but could also be done manually if there is a way to populate the list with all available room names. If so, how do I get these to show up in the XML forms builder. There is a property 'Room' with sub-property 'Name' in the builder's property menu, but I can't see how to use this to get the room name displayed in the form.

Thanks!  After working with the example you sent me, I was able to get it to work -- great!  However, this method seems to overwrite all the other XML in my xfa:data -- not great!
For example, without the script, I have something like this in my form data variable after a form is completed and submitted:
- <xdp:xdp xmlns:xdp="http://ns.adobe.com/xdp/" timeStamp="2010-08-05T15:07:02Z" uuid="62d739de-6eb3-4ae2-8cfc-4eab0dd87f17">
- <xfa:datasets xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
- <xfa:data>
- <root>
- <performanceReview>
<badgeNumber>8107</badgeNumber>
<associateName>NATHAN JANNASCH</associateName>
<department>Information System</department>
<section>IS - System Devlopment</section>
<jobFamily>Professional Staff</jobFamily>
<GLBadge />
<groupLeader />
</performanceReview>
<FSTARGETURL_ />
</root>
</xfa:data>
However, when I use the script as you described above and in your sample to load the data for the dropdown list, I get this in my form data variable:
- <xdp:xdp xmlns:xdp="http://ns.adobe.com/xdp/" timeStamp="2010-08-05T15:10:17Z" uuid="62d739de-6eb3-4ae2-8cfc-4eab0dd87f17">
- <xfa:datasets xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
- <xfa:data>
- <GroupLeaders>
- <GroupLeader>
<GLBadge type="varchar">8103</GLBadge>
<GLName type="nvarchar">AARON MEISTER</GLName>
</GroupLeader>
- <GroupLeader>
<GLBadge type="varchar">5221</GLBadge>
<GLName type="nvarchar">AB EDMONDS</GLName>
</GroupLeader>
</GroupLeaders>
</xfa:data>
It looks like the data the script loads is overwriting all of my other xfa:data.  This is quite bad, as my process is dependent upon this data.  Is there a way to append the dropdownlist data to the xfa:data, or perhaps load it into another node, rather than overwriting the existing xfa:data elements?
Thanks!
