[pmwiki-users] call of EditQuickReference in field

[nexyufuli evo]

hi list
I try to build a custom EditForm with a modified EditQuickReference. So 
I put a EditForm and a EditQuickReference page in the field's wiki.d folder.

The Editform page is loading corect, but not the EditQuickReverence is 
taken of the "master" wikilib.d directory. The call is:
(:include $[{$SiteGroup}/EditQuickReference]:)

If I change it to (:include $[$Site/EditQuickReference]:) the fields 
EditQuickReverence file gets loaded.

So my question: What means $SiteGroup ecactly? The fields Sitepages or 
they of the masterfield of /wikilib.d

Also I noticed that the correct place of the EditForm page is in wiki.d 
not wikilib.d Is there a wikilib.d directory for fields or not?
