    Default Empty folder in TreePanel?

    Empty folder in TreePanel?


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

    Code:
    {
     "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.
    PHP Code:
    $path2['children']    = array();
