[flexcoders] ExpandAll not working for me

[Josh Millstein]

I have no clue on this and it sucks.  Can anybody tell me why my expandAll()
call does not work.  It does not expand the nodes.  Here is my code.  The
ADG is created in actionscript and then grouping is applied to create
hierarchical data.  The last three lines of the following code are where I
call expandAll... after validateNow too.

var oneColumn:AdvancedDataGridColumn = new AdvancedDataGridColumn("FRONTS:
("+firstsFronts.length+")");
                 var twoColumn:AdvancedDataGridColumn = new
AdvancedDataGridColumn("#");
                 var threeColumn:AdvancedDataGridColumn = new
AdvancedDataGridColumn("%");
                 oneColumn.width = 120;
                 twoColumn.width = 35;
                 threeColumn.width = 45;
                 oneColumn.sortable = false;
                 twoColumn.sortable = false;
                 threeColumn.sortable = false;
                 
                 
                 oneColumn.dataField = "FRONT";
                 twoColumn.dataField = "theCount";
                threeColumn.dataField = "thePercentage";
                //twoColumn.width = 20;

[oneColumn,twoColumn,threeColumn];

                indPersonnelDataGridFronts.expandAll();
