    UIDataTable and JSF component binding

    John Manko Newbie

      I'm working on a getting a dynamic table coded, but it doesn't seem to work.  I define a rich:dataTable with a binding to a backing bean property of type UIDataTable, but no columns appear after adding them through code.

                  test after
              </rich:panel>
          </ui:define>
      </ui:composition>
      

       

       

      Managed bean:

      @Named
      @SessionScoped
      public class ListController implements Serializable {
      
          @EJB
          private SessionSearchBeanLocal searchBean;
          private UIDataTable list;
      
          public void searchForList() {
              list = searchBean.findList();
          }
      
          public UIDataTable getList() {
              return list;
          }
      
          public void setList(UIDataTable list) {
              this.list = list;
          }
      }
