Issue with NumberField editor on using disabled allowDecimals and formatting

Hi All,

I am new to ExtJs and using Extjs 4.1.1.

I have created a cellEditing grid with float values in one of the columns, where i want to round of numbers.

The renderer is

Code:

    function change(value) {
      var val = Ext.util.Format.number(value, '0,000');
        if (value > 0) {
            return '<span style="color:green;">' + val + '</span>';
        } else if (value < 0) {
            return '<span style="color:red;">' + val + '</span>';
        }
        return value;
    }

And the editor is

Code:

            editor: {
                xtype: 'numberfield',
                allowBlank: false,
              allowDecimals:false
            }

The problem is, even if i am not changing the value in the cell, it is showing the dirty flag.

I have reproduced the problem at http://ift.tt/1qyUOD0 and tested it. The problem exists there also. I do need to show dirty flag if value is changed, but not when user just clicks the cell, but do not change the value.

Thanks
