Hi Ricardo, Great! :) There’s this doc that you may or may not have seen already: http://platform.xwiki.org/xwiki/bin/view/DevGuide/Scripting Please check in this doc the limitations of using groovy (programming rights). It’s easy to convert a velocity script in groovy in general since the bindings are the same and all the API calls are actually calls on java objects and thus are the same from all scripting languages. Let us know if you have specific questions. Thanks -Vincent

Hi Ricardo, These 2 lines seem wrong: objsAuthors = doc.getObjects('XWiki.XWikiComments').author objsAuthor = doc.getObjects('XWiki.XWikiComments')[2].author doc.getObjects() will return a List of objects (i.e. several), and there’s no getAuthor() or get(‘author’) API on a Vector or List… If you want to iterate you need to: doc.getObjects('XWiki.XWikiComments’).each() { def author = it.get(‘author’) println “* ${author}" } I think the error is that in Velocity the call: $doc.getObjects('XWiki.XWikiComments')[2].author is a shortcut and the real call is: $doc.getObjects('XWiki.XWikiComments')[2].get(‘author’) See http://velocity.apache.org/engine/1.7/user-guide.html#property-lookup-rules This doesn’t exist in Groovy so you need to write get(‘author’). Thanks -Vincent
