[SOLVED] My Codename One form is loading all the parts, then scrolling off the screen to the left, and showing a blank screen in the Simulator

My Codename One form is loading all the parts, then scrolling off the screen to the left, and showing a blank screen in the Simulator

I have added a second form to my app, and it scrolls off the screen to the left in the simulator, leaving a blank form on the screen. In the attached code my call from the splash screen menu is shown first, then my class. I do not see what is flushing my form, as Shai identified what was probably happening with my first form, and I do not know what I did to stop the first form from scrolling off. Does anyone see my error? Thanks.

// Call on Splash Screen
    public boolean openField2() throws IOException {
        Form mbd = new MoveByDrag();
        mbd.show();
       return false;
    }

Solution

I just tried this variation of your code:

TableLayout t2 = new TableLayout(2, 1);
Form playfield = new Form(t2);
Container controls = new Container();
Container field = new Container();
field.getAllStyles().setBgColor(0xff);
field.getAllStyles().setBgTransparency(0xff);
playfield.add(t2.createConstraint().heightPercentage(10).widthPercentage(100), controls);
playfield.add(t2.createConstraint().heightPercentage(90).widthPercentage(100), field);
playfield.show();

It didn't scroll to the side or have any problem I could see. It should be functionally identical. Can you provide screenshots or a video illustrating what you're seeing?
