Strange behaviour with Transitions

Question

I set transitions to a Form :

public class Ecran extends Form {

    private Transition transIn = CommonTransitions.createSlide(CommonTransitions.SLIDE_VERTICAL, true, 250);
    private Transition transOut = CommonTransitions.createSlide(CommonTransitions.SLIDE_VERTICAL, false, 250);

    public Ecran()
    {
        super();
        setTransitionInAnimator(transIn);
        setTransitionOutAnimator(transOut);
    }

    public Ecran(String titre)
    {
        super(titre);
        setTransitionInAnimator(transIn);
        setTransitionOutAnimator(transOut);
    }
}

public class MenuPrincipalForm extends Ecran implements ActionListener, FocusListener, Runnable 
{
   ...
}

The problem is that in runtime the transition slides twice ! So how to make it slide only once ?

Answer 1

Use only the out transition for forms. Transition in allows more elaborate cases for forms and is useful for cases such as dialogs.
