Sorting function not called in Flex Datagrid

Question

Hi all,

I am creating a Datagrid in AS3, and adding a sort function to a column. However, this sort function does never get called. Any ideas?

   dg_gruppenUebersicht = new NestedDataGrid;
   dg_gruppenUebersicht.sortableColumns = true;
   dg_gruppenUebersicht.dataProvider = arrCol_gruppenTnAkt;
   dg_gruppenUebersicht.columns = new Array;
   var cols : Array = dg_gruppenUebersicht.columns;

   //initalize datagrid
   var dgc : DataGridColumn = new DataGridColumn( "Jahrgang" );
   dgc.dataField = "TnJahrgang";
   dgc.labelFunction = MyFormatter.lblfunc_alter2jahrgang;
   dgc.sortable = true;
   dgc.sortCompareFunction = compareFunc_tnJahrgang;
   dgc.headerText = "Alter";
   dgc.headerRenderer = new ClassFactory( at.moschitz.VDGHeader );
   dgc.width = 20;
   cols.push( dgc );

   dg_gruppenUebersicht.columns = cols;

Strangely, the label function gets called.

Thanks Martin

Try calling arrCol_gruppenTnAkt.refresh(); at the end.

Are there other columns in the data grid? If so, did you click on the dgc column so that the grid is sorted as per this column?
