I have been doing alot of work on a custom grid, with built in filtering and dynamic columns and buffered scrolling.
Along the way I noticed something that confused me a little about sorting. Whne you sort based on column you can do remote sorting which passes the field name and the direction either ASC or DESC.

But it is passing the dataIndex field rather than the mapped field. So if I have a record:
var recordmapping = Ext.data.Record.create([
{ name : 'First', mapping: 'RandomFieldFromServerSide1'},
{ name : 'Last', mapping: 'RandomFieldFromServerSide2'},
]);
Then add this to the reader which gets added to the store then declare my columns.

this.columns = [{
id: 'title',
header: "first Name",
dataIndex: 'First',
sortable:true,
width: 250
},{
header: "Last Name",
dataIndex: 'Last',
width: 100,
hidden: false,
sortable:true
}];
Then click to sort, say first name, it will post to the URL whatever that be the parameters sort=First&dir=ASC rather than the mapped field which is what the backend knows about.
So I would think that no matter what it should pass sort=RandomFieldFromServerSide1&dir=ASC
Am I crazy for thinking this is what it should do? or am I doing something wrong?
