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. -----Ursprüngliche Nachricht----- Von: jahid [mailto:ja...@outscore.se] Gesendet: Mittwoch, 4.

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. } 1. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 2.
