* PROCEDURE
Label l = new Label("bla");
System.out.println(l.getBoundsInLocal());
System.out.println(l.getBoundsInParent());

* PROBLEM
BoundingBox [minX:0.0, minY:0.0, minZ:0.0, width:-1.0, height:-1.0, depth:0.0, maxX:-1.0, maxY:-1.0, maxZ:0.0]
BoundingBox [minX:0.0, minY:0.0, minZ:0.0, width:-1.0, height:-1.0, depth:0.0, maxX:-1.0, maxY:-1.0, maxZ:0.0]

* COMMENT
same happens with methos getWidth(), getHeight(), getMaxWidth, ...
Although the controls are painted perfectly, there seems to be no way to retrieve their postions / bounds.
