Their "value" is dynamic, computed by rendering the "script" meta property. You have two options: (1) Render the "script" meta property in the custom displayer and use the data that has been put in the Velocity context (assuming you're using Velocity in the "script" value) {{velocity}} #set ($script = $object.getxWikiClass().get($name).getValue('script')) #set ($classSyntax = $xwiki.getDocument($object.documentReference).syntax) #set ($discard = $doc.getRenderedContent($script, $classSyntax)) ## Assuming $users is set in the "script" meta property $users {{/velocity}} (2) Most of the time you don't need to access the "raw" value of a computed field. If you're only interested in displaying it then it's easier to generate the hyperlinks directly in the "script" meta property. Which is equivalent with leaving the "script" meta property empty and putting all the code in the custom displayer. Hope this helps, Marius
