ComboBox in GoText object

Having trouble getting combo box text to show up in a GoText object in my view.
What am i missing?
// Add combo box control as shape
GoText gt = new GoText(); gt.Location = new PointF(300, 530); gt.Width = 100; gt.Height = 30; gt.EditorStyle = GoTextEditorStyle.ComboBox; ArrayList alist = new ArrayList(); alist.Add("Single"); alist.Add("Triple"); alist.Add("Home Run"); alist.Insert(1, "Double"); gt.Choices = alist; gt.DropDownList = true;
myGraphView.Document.Add(gt);

The combobox is an editor… you have to set the GoText to be Editable.
