    Default TreePanel double click expands not expansible node

    REQUIRED INFORMATION Ext version tested:
    • Ext 4.0.7

    Browser versions tested against:
    • FF 11
    • IE9

    • When making a tree with a node with children, and setting the parent to Collapsible = false, expandable= false,expanded= false, double clicking the node still expands the node

    Steps to reproduce the problem:
    • Make a tree with a node with childnodes, make node expanded: false,expandible:false,collapsible: false, double click node

    The result that was expected:
    • Node not expanded

    The result that occurs instead:
    • Node did expand

    Test Case:
        var store = Ext.create('', {
        root: {
            //expanded: true,
            children: [
                { text: "detention", leaf: true },
                { text: "homework", leaf:false, expanded: false,
                expandable: false,
                collapsible: false, children: [
                    { text: "book report", leaf: true },
                    { text: "alegrbra", leaf: true}
                ] },
                { text: "buy lottery tickets", leaf: true }
    Ext.create('Ext.tree.Panel', {
        title: 'Simple Tree',
        width: 200,
        height: 150,
        store: store,
        rootVisible: false,
        renderTo: Ext.getBody()
    I've added a listener to the treestore:
    store.addListener("beforeexpand",this.beforeExpand, this);
    In the handler I check if the node can expand, if not: return false, otherwise return true. This works.
