Re: [OpenMap Users] best way to access a layer handler and repaint updated data?

Hi Ed,

I think you want to use the MapHandler to find the LayerHandler, and
then get the layers from that to find your layers. Unless your layers
are set to be added to the MapHandler when they are created (and that
doesn't happen by default), they will not be in the MapHandler.

        LayerHandler lh =
this.ourMap.getmBeanHandler().get("com.bbn.openmap.LayerHandler");

        Layer[] layers = lh.getLayers();

etc.

Hope this helps,

Don
