How do I set the text of a TreePanel node in JavaScript?

[paulschofield]

I have added a child node to the TreePanel using appendChild.

selectedNode.appendChild(
{
text: 'Node 1',
leaf: true,
iconCls: '#Briefcase'
}

How can I then change this text once its been added?

I have tried the following but the node text doesn't update until I expand/collpase the parent :

selectedNode.data.text = 'New Text';
selectedNode.set('title', 'New Text');
selectedNode.set("text", 'New Text');
treePanel.store.update();

Is there another way to force the change?

Hello @paulschofield!

The last option you are trying to use looks right. But you didn't provide a runnable test case, all I can do is test with what we have; and I chosen the TreePanel basic example.

There, if I just run App.TreePanel1.getRootNode().getChildAt(0).set('text', 'Bach');, I have the node updated correctly.

You can try by yourself in the example. If you can show the issue or the scenario via a runnable example, we probably could help you better.

Anyway, hope the example above helps you find out what's wrong in your scenario.
