Very crazy. Good research. RIM needs to add this to their test cases before a release. I would hate to add in kludge code to work around this.

FYI - PickerLists do not suffer from the same problem. 

Reworked sample code below.

package
{
	import flash.display.Sprite;
	import flash.events.Event;
	
	import qnx.ui.data.DataProvider;
	import qnx.ui.picker.Picker;
	import qnx.ui.picker.PickerList;
	import qnx.ui.tween.Scroller;
	
	[SWF(height="600", width="1024", frameRate="30", backgroundColor="#FFFFFF")]
	
	public class SliderSample extends Sprite
	{
		private const scrollWidth:Number = 250;
		private const scrollHeight:Number = 45;
		private const monthWidthRatio:Number = 2.1;
		private const dayWidthRatio:Number = 1;
		private const yearWidthRatio:Number = 1.6;
		
		private var arrDay:Array;
		private var arrMonth:Array;
		private var arrYear:Array;
		//private var arrDPs:Array;
		
		private var dpDay:DataProvider;
		private var dpMonth:DataProvider;
		private var dpYear:DataProvider;
		
		private var dayPicker:PickerList;
		private var monthPicker:PickerList;
		private var yearPicker:PickerList;
		
		public function SliderSample()
		{	
			//stage.nativeWindow.visible = true;
			
			arrDay = new Array();
			arrMonth = new Array();
			arrYear = new Array();
			dayPicker = new PickerList();
			monthPicker = new PickerList();
			yearPicker = new PickerList();
			
			/*  Setup the years */
			for (var i:int=1; i<=2050; i++){
				arrYear.push ({label: i});
			}
			dpYear = new DataProvider(arrYear);
			yearPicker.dataProvider = dpYear;
			
			/*  Setup the months January - December */
			arrMonth.push({label: "January"});
			arrMonth.push({label: "February"});
			arrMonth.push({label: "March"});
			arrMonth.push({label: "April"});
			arrMonth.push({label: "May"});
			arrMonth.push({label: "June"});
			arrMonth.push({label: "July"});
			arrMonth.push({label: "August"});
			arrMonth.push({label: "September"});
			arrMonth.push({label: "October"});
			arrMonth.push({label: "November"});
			arrMonth.push({label: "December"});
			dpMonth = new DataProvider(arrMonth);
			monthPicker.dataProvider = dpMonth;
			
			/*  Setup the days */
			arrDay = new Array();
			for (i = 1; i<= 31; i++){
				arrDay.push({label: i, data:i});
			}
			dpDay = new DataProvider(arrDay);
			dayPicker.dataProvider = dpDay;
			

			
			/*  Setup the size and width ratios of
			*  the picker and its columns
			*/
			dayPicker.width = scrollWidth*(dayWidthRatio/(monthWidthRatio+dayWidthRatio+yearWidthRatio));
			dayPicker.height = scrollHeight;
			monthPicker.width = scrollWidth*(monthWidthRatio/(monthWidthRatio+dayWidthRatio+yearWidthRatio));
			monthPicker.height = scrollHeight;
			monthPicker.x = dayPicker.x + dayPicker.width;
			yearPicker.width = scrollWidth*(yearWidthRatio/(monthWidthRatio+dayWidthRatio+yearWidthRatio));
			yearPicker.height = scrollHeight;
			yearPicker.x = monthPicker.x + monthPicker.width;
			
			/* Try to set the date to JUNE 19, 2011 */
			/* Note:Indices are 0-indexed */
			dayPicker.selectedIndex = 18;
			monthPicker.selectedIndex = 5;
			yearPicker.selectedIndex = 2010;
			addChild(dayPicker);
			addChild(monthPicker);
			addChild(yearPicker);
			
			
		}
		
		
	}
}

Note, PickerList seems to have its own problem.  Once populated, the height of the pickerList returns a massive value (i.e. yearPicker.height = 2162), even though on screen it looks fine.  The problem arises when you add the picker on top of a scrollPane.  Now the scrollPane thinks it's scrollContent is huge and creates a long scroll.

This bug was fixed in the 1.1 SDK. Give it a try if you haven't already.
