yes, exactly this is my code : @Out(scope = ScopeType.CONVERSATION) | private List<Assignable> availableLines; | | public void addAssignable() { | if(this.assignable != null){ | System.out.println("removed = "+this.availableLines.remove(this.assignable)); | for(Assignable it : this.availableLines) | { | System.out.println("Lignes Restantes : "+it.getDesignation()); | } | this.lignes.add(assignable); | listeAssignables.put(assignable.getDesignation(), assignable); | Totaux.put(assignable.getDesignation(), new Float(0)); | this.updateTable(); | this.assignable = null; | } | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4112564#...
