Problem in Firefox with dateRenderer on column

[jord1242]

I have a column in a grid that is a date being passed back as:

Sep 23

Here is my code for the column:

{id:'sched',header: 'Sched', width: 50, sortable: true, dataIndex: 'sched_date', renderer: Ext.util.Format.dateRenderer('M d')},

In Chrome this renders correctly, and I can sort the column correctly by date (if I leave that out, it sorts the numbers as text and incorrectly sorts them).

Problem is, in Firefox I am getting the following error:

Date.monthNames[month] is undefined
http://localhost:9005/static/js/extjs/ext-all.js
Line 19

Why would this work just fine in Chrome, but not in Firefox?? Does anyone have a clue on this one? I should be able to use the 'M d' formatter.

Thanks for any input.

Anyone have any ideas on this? I am stumped.

For those that come across this, I was not formatting the date also in the JSONReader:

		reader			: new Ext.data.JsonReader({
							root 			: 'recruits',
							totalProperty	: 'totalCountRecruits'
							},
							[
					           {name: 'source_abbr'},
					           {name: 'source_name'},
					           {name: 'source_sec_abbr'},
					           {name: 'source_sec_name'},
					           {name: 'internet_app'},
					           {name: 'recept_abbr'},
					           {name: 'recept_name'},
					           {name: 'email'},
					           {name: 'recruit_name'},
					           {name: 'recruit_office_id'},
					           {name: 'recruit_id'},
					           {name: 'sched_date', type: 'date', dateFormat: 'M d'},
					           {name: 'rescheduled'},
					           {name: 'noshow'},
					           {name: 'prior_qual'},

					           {name: 'qual'},
					           {name: 'kept'},
					           {name: 'accept'},
					           {name: 'training'}
					        ]
