HI,

I've got a grid with a column to display a formated timestamp (it's actually a LiveGrid, but I get the same issue with regular GridPanels). The value is properly displayed in Chrome, but not in Firefox nor Safari. If I remove the renderer, the raw data is properly displayed and if I change the type of 'stamp' from date to string, I just get NaNs. Any idea?

Code:
var log = Ext.data.Record.create( [
	{ name: 'connexion_log_id',	type: 'int'},
	{ name: 'username',		type: 'string'},
	{ name: 'ip', 			type: 'string'},
	{ name: 'stamp', 			type: 'date'},
]);
Code:
var cmLogs = new Ext.grid.ColumnModel( [
	                {
					    header: ' ',
					    width: 35,
					    fixed:true,
					    align: 'center',
	                    		    menuDisabled:true,
					    sortable: true,
					    groupable: false,
					    editable: false,
					    id: 'numberID',
					    dataIndex: 'connexion_log_id'

	                }, {
	                    header: "Username",
	                    sortable: true,
	                    groupable: true,
	                    width: 150,
	                    id: 'logs_username',
	                    dataIndex: 'username'

	                }, {
	                    header: "IP",
	                    sortable: true,
	                    groupable: true,
	                    id: 'logs_ip',
	                    dataIndex: 'ip'

	                }, {
	                    header: "Timestamp",
	                    sortable: true,
	                    groupable: true,
	                    width: 170,
	                    renderer: Ext.util.Format.dateRenderer('F jS, Y, g:i a'),
	                    id: 'logs_stamp',
	                    dataIndex: 'stamp'

	                }
	        ]);
The data from the server is in JSON format as follows:
Code:
[{"connexion_log_id":"49","username":"thomas.triplet","ip":"127.0.0.1","stamp":"2009-11-03 15:59:54"},{"connexion_log_id":"48","username":"thomas.triplet","ip":"127.0.0.1","stamp":"2009-11-03 15:28:00"}
