Edit: Post topic date should read 30-11-1999 not 13-11-1999

Hi guys,

On a colModel field when I set the paramater formatter to date (formatter:'date' ), date values with 0000-00-00 change to 30-11-1999. Is there anyway to change this?

Sample Code

{name:'event_date_start',index:'event_date_start', align:”right”,editable:true,formatter:'date'}
