Do you mean $xwiki.activitystream. API is broken?

I don't remember talking about the activity stream API :) I

probably because you didn't talk about it :-))

don't really know it well enough to give advices on it.

Finally, I used another method who's working like I want: {{velocity}} #set ($MonStream=$xwiki.activitystream.getStreamName("Sandbox")) ##foreach ($MonEvent in $xwiki.activitystream.getEventsForUser("XWiki.Admin", false, 1500, 0)) #foreach ($MonEvent in $xwiki.activitystream.getEvents($MonStream, false, 1500, 0)) 1. $MonEvent.getPage() - $MonEvent.getDisplayDate() - $MonEvent.getDate() - $MonEvent.getType() - $MonEvent.getPriority() #if ($MonEvent.getPage() == "Sandbox.test3") * Je supprime l'event $xwiki.activitystream.deleteActivityEvent($MonEvent) #end #end {{/velocity}} Like I chatted with Vincent I know groovy is powerfull (except the fact that "With great power comes great responsibility" ;-) ), full example application in groovy missing (because required PR) and templates contains tons of nice velocity code. :-) Thxs for your help / works :-)
