timefield resets after editing

[davedriesmans]

i have a grid with two dates :
{id : 1, agendaTimeFrom: '2011/01/22 09:30', agendaTimeTo:'2011/01/22 11:30', ...

when i submit an edited time, the date resets to 2008/01/01. see row 2:

my view column code

{
            header: 'Time From', 
            dataIndex: 'agendaTimeFrom', 
            renderer: Ext.util.Format.dateRenderer('y/m/d H:i'),
            editor: { 
                        format:'H:i',
                        xtype: 'timefield', 
                        submitFormat : 'y/m/d H:i',
                        increment: 15,
                        minValue: '8:00 AM',
                        maxValue: '7:30 PM',
                            },
            width: 100
},

i use version 4.0.7

I moved this to the bugs forum to open a bug ticket for it as it shouldn't do that.
