    Urgent Help: DnD returns no client ID or client ID hasn't be

    Yizhe Shen Newbie

      Hi guys, I tried to get DnD in 3.1.1 GA to work but it is still throwing me the error whenever I load the page.

      I have this in my JSF

      <h:panelGrid cellpadding="0" cellspacing="5" width="700" border="0" binding="#{ITeventBean.gridElems}"></h:panelGrid>

      This is in my beans:

      public HtmlPanelGrid getGridElems() {
      
       HtmlPanelGrid grid=new HtmlPanelGrid();
      
       System.out.println("OutputText Created");
       HtmlOutputText ot = new HtmlOutputText();
       ot.setValue("test");
       grid.getChildren().add(ot);
      
       System.out.println("DragZone Created");
       HtmlDragSupport myDragZone = new HtmlDragSupport();
       myDragZone.setValue("test123;");
       grid.getChildren().add(myDragZone);
      
       return grid;
       }

          BTW, the error I get is:

          drag:Element with [form:j_id_id55] ID was not found in the DOM tree. Probably element has no client ID or client ID hasn't been written. DnD's disabled. Check please!

            drag/drop support can be attached only to components that output their client ids. Standard JSF components output client ids only if "id" attribute was set explicitly, so you'll have to set it explicitly to get this working.

              Thanks for the reply. I have no problem using drag/drop if I code the stuff all in the JSF. However, when I try to programmatically create it, it will throw the error.

              I research online and it seems to be a bug identified however, they mention that it is fixed in 3.1.1 but I still gets the same problem. If you check

              https://jira.jboss.org/jira/browse/RF-6910

              Anyone has a solution to this? I really need help in this.

                Check your code: you are creating standard component and not setting explicit "id".
