Hi, Thanks for the response. But there are still a couple issues. Here
is a review of my setup again. I have a xwiki manager with a couple
wikis on it. ill call the xem controller wiki "controllerwiki", and
the virtual wikis "wikiA" and "wikiB" This is the code im using:
-------------------------------
#set ($WikiManager = $xwiki.wikimanager)
#set($wikiDesc = $WikiManager.getWikiFromName("wikiA"))
#set($wikiAlias = $wikiDesc.firstWikiAlias)
$wikiAlias
------------------------------
When I put this code in a page called "Test" on the controller wiki, i
get the following:
XWiki.XWikiServerWikiA,wikiA.domain.net,XWiki.Admin
but when i put this code in a page called "Test" in wikiA I get a
stack trace. here it is:
Error number 4001 in 4: Error while parsing velocity page Main.Test
Wrapped Exception: Failed to evaluate content with id Test
com.xpn.xwiki.XWikiException: Error number 4001 in 4: Error while
parsing velocity page Main.Test
Wrapped Exception: Failed to evaluate content with id Test

i really need to be able to get the domain name of the wiki im on with
out knowing its name too, so something that takes the name of the wiki
as an arg probably wont work for me. And suggestions? Thanks.
