[Users] Problem sorting data in a GridPanel by a column

[Riccardo Gaeta]

Thanks Christain, I've tried your tip but it doesn't work for me.
I don't know why but GeoExt persist to put my data in ascendent order by
the "date" column, without ANY specification about that...I don't really
understand.

Any other ideas???

Thanks to all
