In Listgrid : Problem with sorting a datefield (european format)

[Lab]

I'm using SMARTGWT 3.0 build 11 September 2012.
In my listgrid, i have a dateField.
I get listgrid's data by rpc call. In my server side, the format of dateField is dd/mm/yyyy. So in my client side i want to set format "toEuropeanShortDate". But nothing is working.
I tried :
1)
myGrid.setDateFormatter(DateDisplayFormat.TOEUROPEANSHORTDATE);
myGrid.setDateInputFormat("DMY");
--> Not working
2)
DataSourceDateField dateField = new DataSourceDateField("date", "Date");
dateField.setAttribute("inputFormat", "DMY");
dateField.setAttribute("displayFormat", "toEuropeanShortDate");
--> Not working
3)
DateUtil.setDateInputFormat("DMY");
DateUtil.setShortDateDisplayFormat(DateDisplayFormat.TOEUROPEANSHORTDATE);
--> Not working

i have always the same result, when i sort my datefield, the results are sorted as if they are in the format mm/dd/yyyy.
You can see the result of Ascending Sort in the picture attached.

Please help.
Thanks.

Formatting does not affect sort order.

The problem is most likely that you are delivering the date as a String. You need to deliver it as a true Date (java.util.Date or subclass).

Then sorting will work, and formatting will actually be applied (date formatters are not applied to String data).

You are right. In the server side, i deliver my dates as String.
I just modified this as you said and everything works fine.

Thanks a lot for your reply!!
