LinkTree

[Jahid]

Hi,

I have a LinkTree on a page, that page also contains a panel. First time
the page will be loaded with an empty panel. But if user clicks on link,
then i wanted to replace the empty panel with a new panel. but it seems
like its not  working. Below is the part of my code-

   1. public ListContractsPage() {
   2.         add(prepareTree());
   3.         add(new
      EmptyPanel("detailsPanel","").setOutputMarkupId(true));
   4.     }
   5.     private BaseTree prepareTree() {
   6.         DefaultMutableTreeNode rootNode = new
      DefaultMutableTreeNode("Contracts");
   7.         TreeModel treeModel = new DefaultTreeModel(rootNode);
   8.         assembleContracts(rootNode);
   9.         final LinkTree linkTree=new LinkTree("tree", treeModel){
  10.             @Override
  11.             protected void onNodeLinkClicked(Object node, BaseTree
      tree, AjaxRequestTarget target) {
  12.                 Object userObject = ((DefaultMutableTreeNode)
      node).getUserObject();
  13.                 Panel targetPanel;
  14.                 if (userObject instanceof ServiceHandle) {
  15.                     targetPanel = new
      ServiceDetailsPanel<ServiceHandle>("detailsPanel", (ServiceHandle)
      userObject);
  16.                 } else if (userObject instanceof ContractHandle) {
  17.                     targetPanel = new
      ContractDetailsPanel<ContractHandle>("detailsPanel",
      (ContractHandle) userObject);
  18.                 } else {
  19.                     throw new AssertionError("Expected: master,
      sub or service handle, but found: " +
      userObject.getClass().getSimpleName());
  20.                 }
  21.                 targetPanel.setOutputMarkupId(true);
  22.                 target.addComponent(targetPanel);
  23.             }
  24.         };
  25.         return linkTree;
  26.     }


The panel which is added on line3, will be replaced by line15 or line17.
But it seems like its not replacing. I actually debugged, and the
control reaches over there and executes upto line22. But the new panel
was never rendered on browser.

I am using wicket 1.4.2.

Anyone have any idea why new panels are not rendered?

Thanks in advance.

Hi,
  you should have a container and add that container into target.

  This is how i've done this:
        http://xaloon.googlecode.com/svn/trunk/xaloon-wicket-jpa-components/src/main/java/org/xaloon/wicket/component/tree/TreePanel.java

Add you need to replace your old detailsPanel for the new one. Like:
HomePage.this.replace(targetPanel)

Guys, thanks a lot for quick reply. I have changed my code according to
your mentioned way, but seems like i am doing something wrong. Below are
my code, markup and stacktrace -



   1. private WebMarkupContainer markupContainer;
   2.     final String DETAILS_PANEL_ID ="detailsPanel";
   3.     public ListContractsPage() {
   4.         markupContainer =new WebMarkupContainer("markupContainer");
   5.         markupContainer.setOutputMarkupId(true);
   6.         markupContainer.add(new
      Label(DETAILS_PANEL_ID,"label").setOutputMarkupId(true));
   7.         add(prepareTree());
   8.         add(markupContainer);
   9.     }

Hi,

i did another way an that way worked.

Replace markupContainer.add(new Label(DETAILS_PANEL_ID,"label").setOutputMarkupId(true));
with
private final Label labelToReplace = new Label(DETAILS_PANEL_ID,"label").setOutputMarkupId(true);
....
markupContainer.add(labelToReplace);
...
And in onNodeLinkClicked create your panel and then do: labelToReplace.replaceWith(targetPanel);

Hope this helps.
