Hi First of all - Congratulations Ludovic. I am amazed at the usefulness and flexibility of xwiki. Secondly, I have created a xwiki with individual subjects on each page. The data is held in a structured manner in attached objects. Individually they are displaying perfectly with the ClassSheet. However, ideally I want to make collected pages which group the individual subject pages so that any change to the base information, also updates the group documents. Unfortunately, if I include the pages with includeTopic they are not displayed (i think because the relevant object is not referenced). So 2 questions: How would I reference the object so it will display correctly? In the api I can see that you can request the RenderedContent from a page. Could I build a macro that accepted a page name and returned the Rendered Content? (if so how) Cheers, Mark Robinson
