Actually, OMGraphics were modified (in 4.6.1 I think) to have
setAttribute(key, object) and getAttribute(key), so you can associate
as many objects as you want with an OMGraphic.
The setAppObject(...) is still there and still works, the
setAttribute(...) calls work with it, which is why it may have gone
unnoticed.
In OpenMap 4.6.2, labeling has been added to OMGraphics, too, if you
use set an OMLabeler object on an OMGraphic using the OMGraphic.LABEL
key.
