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.

Betreff: Re: LinkTree
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. }
10. private BaseTree prepareTree() {
11. DefaultMutableTreeNode rootNode = new
DefaultMutableTreeNode("Contracts");
12. TreeModel treeModel = new DefaultTreeModel(rootNode);
13. assembleContracts(rootNode);
14. final LinkTree linkTree=new LinkTree("tree", treeModel){
15. @Override
16. protected void onNodeLinkClicked(Object node, BaseTree
tree, AjaxRequestTarget target) {
17. //markupContainer.remove(DETAILS_PANEL_ID);
18. Object userObject = ((DefaultMutableTreeNode)
node).getUserObject();
19. Panel targetPanel;
20. if (userObject instanceof ServiceHandle) {
21. targetPanel = new
ServiceDetailsPanel<ServiceHandle>(DETAILS_PANEL_ID,
(ServiceHandle) userObject);
22. } else if (userObject instanceof ContractHandle) {
23. targetPanel = new
ContractDetailsPanel<ContractHandle>(DETAILS_PANEL_ID,
(ContractHandle) userObject);
24. } else {
25. throw new AssertionError("Expected: master,
sub or service handle, but found: " +
userObject.getClass().getSimpleName());
26. }
27. targetPanel.setOutputMarkupId(true);
28. ListContractsPage.this.addOrReplace(targetPanel);
29. target.addComponent(targetPanel);
30. }
31. };
32. linkTree.setOutputMarkupId(true);
33. linkTree.getTreeState().expandNode(rootNode);
34. return linkTree;
35. }

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

Hi,
you should have a container and add that container into target.
This is how i've done this:

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.
