    MultipleDataSelection and problem with merge

    yohann Normandin Newbie

      Hi everybody !

      I currently develop an enterprise application able to manage a client's account(he could see his orders, line orders and product in assocation with those lines). I use netbeans, glassfish, seam and hibernate. I want to post many datalist with link. I use Conversation and Session for that. I want to know if it possible to use many DataModeleSelection.

      Otherwise theirs is a problem with my ServerManger :

      first page : login
      second : list of orders
      third : list of lines
      forth : list of server concerned by the lines

      
      Code of my forth page
      Stateful
      @Name("ServerManager")
      
      public class ServerManager implements ServerManagerLocal
      {
      
      
       @In
       private EntityManager em;
      
       @DataModel
       @In(required=false) @Out(required=false)
       List<Server> servs;
      
      
       @DataModelSelection
       @Out(required=false)
       private Server currentServer;
      
      
       private OrderLine myOrderLine;
      
      
       @Factory(value="servs",scope=CONVERSATION)
       public void searchServers (){
      
      
       servs = myOrderLine.getServers();
      
      
       }
      
      
       @Begin(join=true)
       public void viewParameters(OrderLine orderLine){
       System.out.println("on rentre dans le server manager");
       myOrderLine=em.merge(orderLine);
      
      
       }
      
      
      
      
      
       @Remove @Destroy
       public void destroy(){
       }
      
       public List<Server> getServs() {
       return servs;
       }
      
      
      
       public Server getCurrentServer() {
       return currentServer;
       }
      
       public void setCurrentServer(Server currentServer) {
       this.currentServer = currentServer;
       }
      
       public OrderLine getMyOrderLine() {
       return myOrderLine;
       }
      
       public void setMyOrderLine(OrderLine myOrderLine) {
       this.myOrderLine = myOrderLine;
       }
      
      
      }
      
      


      And in my debug page I have this exception
