 if i click a node the child is created under the node but doesn't expanded
 but when i click it second time then it expands but with two child.
 

For me 

@Override
protected void onNodeLinkClicked ( AjaxRequestTarget pTarget, TreeNode
pNode) {
[...]
myNavigationTree.getTreeState().expandNode ( pNode); 
[...]
}

solved that problem. Where pNode is the (sub-tree-) root node under which
new nodes have been added dynamically.

Problem with dynamic insertion to Tree

2009-01-15 Thread PSkarthic 

I have a problem in inserting/adding nodes dynamically to tree.

When i inserted/added a node on click, the plus icon appears but it is not
expanded, that is it is not showing the child node i have tried tree.update
but not worked.

My Code
protected void onNodeLinkClicked(org.apache.wicket.ajax.AjaxRequestTarget
target,
javax.swing.tree.TreeNode node){
   
MyTreeNode nd = (MyTreeNode)node;
//nd.add(new DefaultMutableTreeNode(sample));
System.out.println(node + Ajax Clicked);
nd.insert(new MyTreeNode(node + child), 0);
   
//this.modelChanged();
//this.nodeExpanded(node);
this.updateTree();
   
   
}

Why it is happening like.



Thanks
Karthic

what about call target.addComponent(this);

?

you have updated tree but you didn't tell wicket to update this component
visually...
