REQUIRED INFORMATION

Ext version tested:

Ext 4.2.0 Beta

Browser versions tested against:

IE10
Chrome 23

DOCTYPE tested against:

Description:

If you create a grid with all columns hidden by default then you get a Javascript error.
This worked in previous versions.

Steps to reproduce the problem:

Create a grid with all columns set to hidden:true.
Load page.

Test Case:

Code:

    Ext.define('MyApp.view.Viewport', {
        extend: 'Ext.container.Viewport',




        layout: {
            type: 'fit'
        },




        items: [
            {
                xtype: 'gridpanel',
                title: 'My Grid Panel',
                columns: [
                    {
                        xtype: 'gridcolumn',
                        hidden: true,
                        dataIndex: 'string',
                        text: 'String'
                    },
                    {
                        xtype: 'numbercolumn',
                        hidden: true,
                        dataIndex: 'number',
                        text: 'Number'
                    },
                    {
                        xtype: 'datecolumn',
                        hidden: true,
                        dataIndex: 'date',
                        text: 'Date'
                    },
                    {
                        xtype: 'booleancolumn',
                        hidden: true,
                        dataIndex: 'bool',
                        text: 'Boolean'
                    }
                ]
            }
        ]
    });




    Ext.application({
        autoCreateViewport: true,
        name: 'MyApp'
    });

HELPFUL INFORMATION

Debugging already done:

Error occurs on line 151084 of ext-all.js.
The error is caused because the variable lastVisibleColumn is undefined when all columns are hidden (due to the loop above only assigning visible columns to it).

Possible fix:

Check for undefined before accessing lastVisibleColumn.

Operating System:

Windows 8 Enterprise
