Hi Moritz,

It does work here.

My store looks something like this:

new Ext.data.JsonStore
({
	id:'mystore',
	url: /url/for/rest/api
	remoteSort:true,
	listeners:
	{
		load: function() { this.loadingBox.hide(); },
		beforeLoad: function()
		{
			this.loadingBox = Ext.Msg.wait('Loading');
		},
                 exception: function(d,s,a,o,r)
		{
			this.loadingBox.hide();
			Ext.Msg.show
			({
				title:'Error',
				msg:'Failed to load grid data',
				icon:Ext.MessageBox.ERROR,
				buttons:Ext.Msg.OK
			});
                 },
		metachange:function(store, meta)
		{
			var newColumnModel = new Ext.grid.ColumnModel({columns:meta.fields});
			Ext.getCmp(gridId).reconfigure(store, newColumnModel);
		}
	},
	reader: new Ext.data.ArrayReader
	({
		totalProperty:'total',
		successProperty:'success',
		root:'data'
	})
})


I agree that 'header' is not mentioned as a property of a form.field, 
perhaps because it is not and therefore it is just ignored??

However when the ColumnModel is built using 'meta.fields' 
Ext.grid.ColumnModel does not ignore the property and therefore fills 
out the column headers correctly.
