    Several comments:

    Is this UX compatible with 3.1? There is no information concerning this.
    Have you included these files in your uses?
    Have you tried to contact the author?

    We typically do not debug components from other sources.

    Default Ext.tree.TreePanel data load problem

    Ext.tree.TreePanel data load problem


    Hi ,

    I am using this component Ext.tree.TreePanel. When you load Json String this line root.firstChild.expand(false), and this Ext.get('exp') is null or not an object. How to solve this problem.


    root.expand(false, false, function() {
    root.firstChild.expand(false);
    Ext.get('cn').dom.value = tree.getChecked().join(',');
    ser();
    });


    Ext.get('exp').on('click', function() {
    tree.expandAll();
    });



    Thanks & Regards
    Ramesh

    What is 'cn' and 'exp'? DOM elements? Are you sure you should not be using Ext.getCmp()?
