Re: [OpenMap Users] vehicule tracking

When you have your OMGraphicList, if you are working in an object

OMGraphicHandler calling the method getReceiver(); the OMGraphicHandler
has a method setList().

If you can't get a valid OMGraphicHandler probably you have to setup
correctly your loader class.
