    Drag and Drop Over h:datatable

    test test Newbie

      Hi all,

      I'm Newbe with richfaces and I'd like to use the drag and drop solution.
      So I try the Livedemo and I download the code to execute on my own machine.
      It work fine. But when I try to use the same for my application. I have a problem. In the Listener class, when I try to get the getDragValue(), it always NULL.

      This is the code.
      ---------------------

      public void processDrop(DropEvent dropEvent) {
      Dropzone dropzone = (Dropzone) dropEvent.getComponent();
      System.out.println("dropEvent.getDragValue : "+dropEvent.getDragValue()+ " et :"+ dropzone.getDropValue());
      System.out.println("-> "+dropEvent.getDragType());
      System.out.println("--> "+dropzone.getAcceptedTypes());
      dndBean.moveFramework(dropEvent.getDragValue(), dropzone.getDropValue());
      }

      this is my jsf page :
