hello, when I wrote this : | System.out.println("test pour voir tasks"); | Collection tasks= (Collection) swimlane.getTasks(); | Iterator ittasks= tasks.iterator(); | while(ittasks.hasNext()){ | TaskInstance task=(TaskInstance)ittasks.next(); | System.out.println("tache de ernie: "+task.getName()); | } I have a nullpointeur error (particularly on swimlane.getTasks()) have you some ideas why? have i forgotten anything ?? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3971005#...
