Well you can see progress of my experimentation based on xwiki platform there: http://apeiron.lirmm.fr:9006/xwiki I develop a plugin to annotate documents and use it to debate. And I still have some questions: How to add an url to an annotation (my plugin) ? Indeed we want to add annotation to annotation. And so we need to open an annotation as a document in xwikicontent div. Currently, to see the annotation form you need to get comment right. I have set this right allowed to xwikiallgroup. But, if you don't have the edit right, you cannot submit the form. Submitting the form call the method : $doc.getURL('objectadd') So how can i resolve this problem? Maybe creating a new method to add annotation? But how to do that? And last question, where can i see wiki editor comportment? Thank for your time Antoine SEILLES
