No sort direction change in grid with datastore

Hi
I try to use Grid with datastore+dataconnector+ dataprocess with form binding
I use Smartrendering and dynamic_loading .
I have configured Setcolsorting with connector how you see below :
clienti_grid.setColSorting(“connector,connector,connector,connector”);

Grid run well but when i click on Grid sorting header the sort direction is always ASCENDING no change direction is performed .
Log file result :

Log started, 05/01/2013 02:01:20

SELECT FIRST 10 SKIP 29 * FROM TAN$ANAGR ORDER BY NOMINATIVO ASC

Done in 0.020676136016846s

There is a problem or is necessary to make a particular setting to get a sorting change??

Many thanks
Antonello

Unfortunately the issue cannot be reconstructed locally.
If issue still occurs - please, provide a complete demo where the issue can be reconstructed.

Pheraps the problem is this ( bold)??
Datastore.js content file

if (rule && rule.sort)	
		grid.attachEvent("onBeforeSorting", function(ind, type, dir){
	[b]	  if (type == "connector") return false;[/b]
			var id = this.getColumnId(ind);
			source.sort("#"+id+"#", (dir=="asc"?"asc":"desc"), (type=="int"?type:"string"));
			grid.setSortImgState(true, ind, dir);
			return false;
		});

many thanks
Antonello

Please, try to use the following code:

grid.sync(datastore, {sort: true});

Hi,

I have tried grid.sync(datastore,{sort:true});
but the problem is always the same …

It seems do not save the active direction

Any idea ??
