Thanks Sergui, works perfectly when I make that change. 
Odd thing, those classes were created quite some time before the virtual wiki setup was implemented - would have thought they should not be affected by that.
 
Almost a bug though:  as an administrator, if I trust a user sufficiently that I grant them admin rights to the virtual wiki, they really should be able to do anything on that wiki, regardless of whether they exist on the main wiki or not; might just be me though thinks that way!

AFAIK:
The API you are using requires programming rights, and these rights are only possible for users in the main wiki. Try this:
- Create an account on the main wiki, with an username that does not exist in the other virtual wikis
- Grant Programming rights to that user
- Login with that user
- Edit and save the pages that list the users

Now it should work.

Hi all,

Me again, this time with another groups/permission issue.

On my wiki's I use "$context.xWiki.groupService.listGroupsForUser($context.user, $context.context))" to get a list of groups a user is a member of.  This has worked very well up until implementing a virtual wiki setup…since implementing a virtual wiki setup, I've found the listGroupsForUser only works for the main wiki (the one pointing to xwiki database), and not for the "other" wiki's hanging on the same server.

The users are definitely regarded as being in the group as a permission check works for the group (eg if only group ABC has right EDIT for a space, the user is granted the right only if they are in the group).

But, the listGroupsForUser always returns no groups, even for XWiki.Admin - even though every user has at least one group.
