[xwiki-users] accessing to document running macro

Hello, I develop a macro which display object attached to the current page. Here summary of my code: {{goovy}} def topic = doc.getObject("ActivityReport.TopicClass", Integer.valueOf(xcontext.macro.params.id)) println "|"+doc.displayPrettyName("topic", title)+"|"+topic.get("title") println "|"+doc.displayPrettyName("topic", action)+"|"+topic.get("action") println "|"+doc.displayPrettyName("topic", status)+"|"+topic.get("status") {{/groovy}} In my macro page, I put one instance of my TopicClass for development. That working fine. In an other page I put an other instance and call my macro. It display instance from macro page !!! I suppose that I should not used doc to find current document in macro. But I don't find in http://platform.xwiki.org/xwiki/bin/view/DevGuide/WikiMacroTutorial how to retrieved current document. I also test xcontext.doc, but it is same as doc. So how can find current document (the document which call my macro)? Regards, Arnaud.
