一定要用 frame 嗎？
如果可以接受別的做法的話，可以參考一下 ajax tree 的做法：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

Tree myTree= new Tree("myTree", myTreeModel) {   @Override   protected void onNodeLinkClicked(AjaxRequestTarget target, TreeNode node) {     Object userObject = getUserObject(node);     Panel rightPanel = new MyRightPanel("rightPanelId", userObject);     rightPanel.setOutputMarkupId(true);     getPage().replace(rightPanel);     target.addComponent(rightPanel);   } }; add(myTree);   add(new MyRightPanel("rightPanelId", ....)) ;

Html template:

1 2	<div wicket:id="myTree">my tree</div> <div wicket:id="rightPanelId">a panel replaced by clicking tree node.</div>

我省掉一些 code，但大概是這個意思...

frame... 從來沒用過....
