Default The question for DIRECTION !

Please Login to Remove!

Hi all,
I have a sample for DIRECTION.
The first, i declare two objects for display on BlackBerry Screen.
private Screen _secondaryScreen;
private MainScreen mianScreen;
I use transiton to switch between two screen.
I want mainScreen always display on LANDSCAPE mode (Horizontal) by use
Ui.getUiEngineInstance().setAcceptableDirections(D isplay.DIRECTION_EAST), and _secondaryScreen always display on PORTRAIT mode (Vertical) by use
Ui.getUiEngineInstance().setAcceptableDirections(D isplay.DIRECTION_NORTH).
But both mianScreen and _secondaryScreen always display on LANDSCAPE mode. I don't know why. I Hope you can help me, thank you very much !

this is my code.

Code:
import net.rim.device.api.ui.*;
import net.rim.device.api.ui.component.*;
import net.rim.device.api.ui.container.*;
import net.rim.device.api.ui.decor.*;
import net.rim.device.api.system.Display;

public class ScreenTransitionSample extends UiApplication implements
FieldChangeListener 
{
	private ButtonField buttonField1;
	private ButtonField buttonField2;
	private Screen _secondaryScreen;
	private MainScreen mianScreen;
	//private Runnable _popRunnable;
	public static void main(String[] args) 
	{
		ScreenTransitionSample theApp = new ScreenTransitionSample ();
		theApp.enterEventDispatcher();
	}
	public ScreenTransitionSample () 
	{
		_secondaryScreen = new FullScreen();
		_secondaryScreen.setBackground(BackgroundFactory.createSolidBackground(Color.LIGHTBLUE) );
		buttonField1 = new ButtonField("Transition To MainScreenn",ButtonField.CONSUME_CLICK);
		buttonField1.setChangeListener(this);
		_secondaryScreen.add(buttonField1);
		
		TransitionContext transition = new TransitionContext(TransitionContext.TRANSITION_SLIDE);
		transition.setIntAttribute(TransitionContext.ATTR_DURATION, 1000);
		transition.setIntAttribute(TransitionContext.ATTR_DIRECTION,TransitionContext.DIRECTION_RIGHT);
		transition.setIntAttribute(TransitionContext.ATTR_STYLE,TransitionContext.STYLE_PUSH);
		UiEngineInstance engine = Ui.getUiEngineInstance();
		engine.setTransition(null, _secondaryScreen, UiEngineInstance.TRIGGER_PUSH,transition);
		transition = new TransitionContext(TransitionContext.TRANSITION_FADE);
		transition.setIntAttribute(TransitionContext.ATTR_DURATION, 1000);
		transition.setIntAttribute(TransitionContext.ATTR_KIND,TransitionContext.KIND_OUT);
		engine.setTransition(_secondaryScreen, null, UiEngineInstance.TRIGGER_POP,transition);
		mianScreen = new MainScreen();
		mianScreen.setTitle("Screen Transition Sample");
		buttonField2 = new ButtonField("Transition To SecondaryScreen",ButtonField.CONSUME_CLICK) ;
		buttonField2.setChangeListener(this);
		mianScreen.add(buttonField2);
			
		int direction = Display.DIRECTION_EAST;
		Ui.getUiEngineInstance().setAcceptableDirections(direction);
                pushScreen(mianScreen);
	}
	public void fieldChanged(Field field, int context) //overide
	{
				
		if(field == buttonField1)//Transition To MainScreen
		{
			popScreen(_secondaryScreen);
			int direction = Display.DIRECTION_EAST;
			Ui.getUiEngineInstance().setAcceptableDirections(direction);
			pushScreen(mianScreen);
		}
		else if(field == buttonField2) //Transition To SecondaryScreen
		{
			popScreen(mianScreen);
			int direction = Display.DIRECTION_NORTH;
			Ui.getUiEngineInstance().setAcceptableDirections(direction);
			pushScreen(_secondaryScreen);
		}
	}
}
