Does Orbeon Forms support Calendar Navigator?

Hi, All,
I modified the code in xforms.js : A = new YAHOO.widget.CalendarGroup(K.id,{navigator:true}); The navigation control can be displayed, but the input focus of Month and Year will be moved to the date input field automatically. So I can not select the Month and input the year through the navigation control at all. Is this caused by Orbeon Forms or something else? Thank you for your suggestions!
