<!> Exception: if(outOfBound) dialog.close(); - blackberry

Question

Can I close itself in a dialog if touch event happens out side of the dialog field? I can close it quite well on the opposite case as following code shows:
protected boolean touchEvent(TouchEvent message)
{
int x = message.getX( 1 );
int y = message.getY( 1 );
if( x < 0 || y < 0 || x > getExtent().width || y > getExtent().height ) {
// Outside the field
// close();//? can't be closed properly
return false;
}
switch( message.getEvent() ) {
case TouchEvent.UNCLICK:
close();//? can be closed properly
return true;
}
return super.touchEvent( message );
}

Answer 1

try this one.
instead of writing just close write this. hope it will work.
UiApplication.getUiApplication().invokeLater ( new Runnable()
{
public void run ()
{
UiApplication.getUiApplication().pushScreen(new MyTripScreen());
close();
}
}
);

Solved! Thank you all the same.
It is of great help if you can talk to some one when get stuck.
But I still have no ideas what's the difference between these two:
protected boolean touchEvent(TouchEvent message)
{
int x = message.getX( 1 );
int y = message.getY( 1 );
boolean isOutOfBounds = false;
if( x < 0 || y < 0 || x > getExtent().width || y > getExtent().height ) {
// Outside the field
// close();//!
// return true;
isOutOfBounds = true;
}
switch( message.getEvent() ) {
case TouchEvent.UNCLICK:
// close in TouchEvent, if out of bounds
if(isOutOfBounds)
{
close();
return true;
}
close();
return true;
}
return super.touchEvent( message );
}
