Hi, I write this code
Code:
var corm_plSore  = new Ext.data.GroupingStore({
	reader: new Ext.data.JsonReader({
	fields: [
	'name',
	'dim',
	'plan1',
	'plan2',
	'plan3',
	'plan4',
	'plan5',
	'plan6',
	'plan7',
	'plan8',
	'plan9',
	'plan10',
	'plan11',
	'plan12',
	'ag_plan',
	'year',
	'group',
	'farms',
	'srt_gr_index'
		],
	root: 'rows'
	}),
	proxy: new Ext.data.HttpProxy({
			url: 'Ps/st_cormPlan.php',
			timeout: 50000000 	}),
	sortInfo:{field: 'srt_gr_index', direction: "ASC"},
        groupField:'group'
				
	});
Groups is sorting ASC by default, but i need that my groups will be sorting by field
"srt_gr_index"
Can i do this without any perversions ?
