Hi
    Why the following code has no effect to add highlight?

EditorCookie ec =3D dataObject.getLookup().lookup(EditorCookie.class);
Document doc2 =3D ec.getDocument();
OffsetsBag bag =3D new OffsetsBag(doc2, true);
AttributeSet defaultColors =3D AttributesUtilities.createImmutable(StyleCon=
stants.Background, new Color(0, 0, 255));
bag.addHighlight(5, 10, defaultColors);
AttributeSet defaultColors2 =3D AttributesUtilities.createImmutable(StyleCo=
nstants.Foreground, new Color(0, 255, 255));
bag.addHighlight(2, 5, defaultColors2);

Thanks
From Peter
