MenuButton styles

[Alejandro Vilar]

Hi, I'm having some problems with MenuButton styles, particularly with 
focusable and opaque,
I can't assign those values at runtime, for example:

Code:
public static void main(String[] args) {
       MenuButton menuButton = new MenuButton();
       menuButton.getStyles().put("focusable", Boolean.FALSE); // 
doesn't work
       menuButton.getStyles().put("opaque", Boolean.FALSE); // doesn't work
       menuButton.getStyles().put("color", Color.BLACK); // it works
}
Console output:
"focusable" is not a valid style for org.apache.pivot.wtk.MenuButton
"opaque" is not a valid style for org.apache.pivot.wtk.MenuButton

(Seen in pivot 1.3/1.4)

Thanks in advance
