Beta4 breaks my setEditorTemplate code - Please help

I was using code in beta3 to associate a combo box with a grid cell. When the user double clicked to edit the grid cell the combo box would display.

Here is that block of code:
var AccessCombo = new AW.UI.Combo;
AccessCombo.setItemText(["Active","Inactive"]);
AccessCombo.setItemCount(2);
grid.setEditorTemplate(AccessCombo, 6);

The last line is the one causing the problem. I know the cell editing changed in beta 4 but I don't know what I should use instead.

I've searched the forum and examples but didn't find a beta 4 sample.

Thanks,
Rob

The same problem exists in RC1.

Perhaps one need to define an action that will switch the template (setCellTemplate) to that of the combo.
