I think this is a bug in wikimanager.getWikiFromName("wikiA"), it
seems it looks in current wiki in place of forcing search in main wiki
for the wiki descriptor (I just added a jira issue
http://jira.xwiki.org/jira/browse/XAWM-88).
1 - A workaround is to get the descriptor "by hand": all wikis
descriptor are in the main wiki with the name
xwiki:XWiki.XWikiServer<Wikiname> with an upper case for the first
character of the wiki name. The velocity code to get the current wiki
descriptor is something like:
#set($wikidescriptor =
$xwiki.getDocument("xwiki:XWiki.XWikiServer${context.database.substring(0,
1).toUpperCase()}${context.database.substring(1).toLowerCase()}"))
and then $wikidescriptor.server give the domain of the first alias (To
get other alias you have to list document's objects of type
"XWiki.XWikiServerClass")
2 - Another solution if your have progrmming rights is simply to
switch to main wiki using $context.setDatabase() before executing
wikimanager plugin code and restore current wiki when it's done:
#set($currentDatabase = $context.database)
$context.setDatabase($context.mainWikiName)
[...]
$context.setDatabase($currentDatabase)

The current wiki is in $context.database
