Hi all,

I try to simply remove 4 childs from a treeNode and set them in an other one ... but when I use MultiSelectionModel with more than one selection, I got an obscure error ('b is undefined')

Here is a sample :
Code:
var nodes = new Ext.tree.TreeNode({
        id : 'root',
        id: 'test',
        text: 'test'
    });
    var node1 = new Ext.tree.TreeNode({
        id : 'node1',
        text: '1',
        test: new Ext.form.FormPanel()
    });
    var node2 = new Ext.tree.TreeNode({
        id : 'node2',
        text: '2',
        test: new Ext.form.FormPanel()
    });
    var node3 = new Ext.tree.TreeNode({
        id : 'node3',
        text: '3',
        test: new Ext.form.FormPanel()
    });
    var node4 = new Ext.tree.TreeNode({
        id : 'node4',
        text: '4',
        test: new Ext.form.FormPanel()
    });
    nodes.appendChild(node1);
    nodes.appendChild(node2);
    nodes.appendChild(node3);
    nodes.appendChild(node4);

    var tree1 = new Ext.tree.TreePanel({
        id : 'tree',
        animate: false,
        autoScroll: true,
        title: 'Title',
        height: 300,
        width: 150,
        selModel: new Ext.tree.MultiSelectionModel({}),
        enableDD: true,
        rootVisible: false,
        root: nodes,
        loader: new Ext.tree.TreeLoader(),
        dropConfig: {
            allowContainerDrop: true
        }
    });
    
    var button = new Ext.Button({
        id: 'addbutton',
        text : 'copy',
        height: 32,
        width: 32,
        handler: function(){
            var selModel = tree1.getSelectionModel();
            var selection = selModel.getSelectedNodes();

            if (selection.length > 0) {
                var sourceRootNode = tree1.getRootNode();
                Ext.each(selection, function(node){
                    //console.log(node);
                    sourceRootNode.removeChild(node);
                });
            }
        }
    });
    
    var panel = new Ext.Panel({
        layout: 'form',
        items: [tree1, button],
        renderTo: Ext.getBody()
    });
I cannot figure out why my 'selection' array is not correctly filled as soon as I remove a node from the rootnode ...

What mistake did I make ?
Thank you.
