Sort DataGrid by column after save (AS3/spark)

[HGoldman]

I have a spark DataGrid, where the user can sort the row by clicking the column headers... as expected. When they double click a row, it go to an edit. After clicking the save (or back button
[not the browser back button]) the are returned to the updated datagrid. I want to retain the sorting they had before the edit. Here is code I have to capture the sort column.

protected function onSortChange(event:GridSortEvent):void
				
	{
		app.sortColumnIndices = event.columnIndices;
		app.sortColumnName = event.newSortFields[0].name;
	}

This does get the column name and columnIndices as expect. When the screen refreshes with the DataGrid, I have the follow code, which is being executed:

				if (app.sortColumnIndices){
					
					dg.sortByColumns(app.sortColumnIndices);
					var sortColumnName:SortField = new SortField(app.sortColumnName,true);
					sortColumnName.setStyle("locale","en-US");
					
					sort.fields = [sortColumnName];
					
					entitiesDP.sort = sort;
					entitiesDP.refresh();
				}	

				dg.dataProvider = entitiesDP;

The app.sortColumnIndices and app.sortColumnName both contain the "previous" values that I want to use in the sort.

The problem is the DataGrid displays in the original, unsort order..... HELP! PLEASE!

Thanks-
