[xwiki-users] problem with doc.display - trying to set permissions based on a group

Hello everyone. I'm currently developing my skills with velocity to be able to make more advanced applications. Today what I'm trying to do is set some rights based on a modified version of FAQ Application. I've added just a Group field, so the user can direct his question to one of our departaments/groups. What I'm trying to accomplish is: A user creates a FAQ question, but only himself and a Group he chooses are able to view and edit the page. #set ($mydoc = $xwiki.getDocument("FAQ.$doc.name")) #set ($rightsObject = $mydoc.getObject("XWiki.XWikiRights", true)) #set ($result = $rightsObject.set("groups", $doc.display("group", "view"))) #set ($result = $rightsObject.set("levels", "edit")) #set ($result = $rightsObject.set("users", "")) #set ($result = $rightsObject.set("allow", 1)) $mydoc.save() Problem: The object created with doc.display("group") gets the group with the all the wiki markup, when it should be getting only the text "Sales". What I get: {{html clean="false" wiki="false"}} <ul class="users">... What I want: Sales I can easily set the user permission. The big problem is setting the group. Can you help me with this? Thanks. Att, Leonardo.
