[xwiki-users] Updating xwiki objects? How to?

Hello, i have a form that is trying to update xwiki object. For whatever reason, it's not updating. Here is the groovy code. The nearly same code but with "newObject" instead of "getObject" properly create new entries. I can't find out how to tell xwiki that the object has changed and need to be updated in database. if (request.update !=null){ println ("update mode"); obj = doc.getObject('Configuration.NewsClass',request.doEdit.toInteger()) println "$obj " // Here i get "com.xpn.xwiki.api.Object@69506371" obj.set("linkfr",request.linkfr) obj.set("titlefr",request.titlefr) obj.set("linknl",request.linknl) obj.set("titlenl",request.titlenl) obj.set("publication",new java.util.Date().parse("dd/MM/yyyy HH:mm",request.publication)) println obj.get("linkfr"); // Correclty outputs the new value doc.save("update news entries") // This properly appear in history println "Saved "+request.doEdit // It says "Saved 53" for example Regards, David Delbecq
