I get an OMGraphicList from the OMGraphicHandlerLayer using getList and
I iterate through the OMGraphicList and find the graphic(s) I want to
label. These are just plain "OMGraphic"s.
Then all I am doing is:
OMTextLabeler tl = new OMTextLabeler(hasc_code,
OMTextLabeler.JUSTIFY_CENTER);
omg.putAttribute(OMGraphicConstants.LABEL, tl);
Is this a viable way of adding a text label to a graphic?
Do I need to update the OMGraphicList via the OMGraphicLayerHandler
after the label is added?

Hi John,
Looks OK to me, what kind of OMGraphic are you using? I don't think it
works for an OMGraphicList, because the OMTextLabeler piggybacks on the
projected location of the OMGraphic, and the OMGraphicList doesn't
really know where its OMGraphics are.
