Re: [OpenMap Users] adding OMGraphics on the fly

The only thing I can think of is that the OMGraphicList you are adding
the graphic to isn't the one being painted, but you are returning that
same OMGraphicList object in the prepare() method.

The OMGraphicHandlerLayer has it's own OMGraphicList variable that gets
set with the one returned from the prepare() method. That list may be
null. You can get it by calling getList() at the point where you add
your line.
