Issue with Carousel in a Dialog Box, scrollbar doesnot appear

Hi

I am trying to add a Carousel containing many Forms (with too many Form Elements) to a Dialog Control (desktop controls) , however I seem to have a problem with the scrollbar on the Dialog Box. It does not appear and hence scrolling thru the Form UI Elements is difficult.

If I just add the Form to the Dialog - a nice vertical scroll appear.

The moment I add the Form to the Carousel and add it to the Dialog - the scroll disappears. And that makes navigating thru the form impossible. 

Here is the dialog

var oCarousel = new sap.ui.commons.Carousel({ enableScrolling: true});

            oCarousel.setWidth("95%");

            oCarousel.setHeight("95%");

            oCarousel.setVisibleItems(1);

         //   enableScrolling: false,

            oCarousel.setHandleSize(15);

           // oCarousel.defaultItemHeight("100%");           

            oCarousel.setOrientation("horizontal");

oCarousel.addContent(form);

callDialog.addContent(oCarousel);

What could be a problem here?

Regards
