v2.0.2 combo in grid problem using UI.List on firefox

we were using the V2 version with no problems, just downloaded the v2.0.2 trial version and notice different behaviour on firefox

var myList = new AW.UI.List;
myList.setItemText( * set the content string with 4 items *);
myList.setItemCount(4);
obj.setCellTemplate(new AW.Templates.Combo, 3);
obj.setPopupTemplate(myList, 3);

on v.2.0.2 on firefox, when i click the V for the drop down list, the previously selected item blanks out. when i select an item from the list, the combo closes and goes away, but the grid still shows blank.

is there any change to the way the combo template works?

it works fine on IE. i am using firefox 1.5

thanks!
