Empty folder in TreePanel?

[bbxx]

I'm getting strange behavior when adding a folder with no children to a treepanel.

{
 "text":"Empty Folder",
 "id":4,
 "position":2,
 "leaf":false,
 "cls":"folder"
}

When I click on the folder, it expands and then the whole treepanel appears under this folder.

How do I add an empty folder? It's empty now, but I want to add to it later with drag/drop.

THe URL you load from must provide the correct children based on the passed id

Yes, but that is the problem: I don't want the folder to have any children initially. The URL should return a folder with no children. It will only have children later, when I drag/drop on the client side.

Right. So you know why you have a problem then.

Yes, I know why I have a problem, but I don't know how to fix it - that's why I came here. How do I indicate that there are no nodes on a folder?

The server script that you specify in the loader returns the array of child nodes when passed the id.

You must return []

Thank you! I got it working by returning an empty array as you suggested.

$path2['children']    = array();
