i have use property locked in treepanel column, and my console report problem :

    columns: [{
        xtype: 'treecolumn', //this is so we know which column will show the tree
        text: 'Task',
        locked:true,
        flex: 2,
        sortable: true,
        dataIndex: 'task',
    }

ERROR IS: ext-debug.js:10872 Uncaught TypeError: Cannot read property 'length' of undefined

  • Not sure if this is the issue but you have an extra comma after `dataIndex: 'task'`. – neo108 Mar 20 '12 at 02:58
