[flexcoders] DataGridColumn sortDescending property doesn't change after first two clicks on header

[Sergey Kovalyov]

Hi All!

I have defined my own handler for the headerRelease event in order to
perform custom server-side sorting, since my DataGrid is pagable. In order
to do that I get the field from event.dataField and and order from
DataGridColumn(DataGrid(event.target).columns[event.columnIndex]).sortDescending,
though sortDescending is false after first and second clicks. Why?
