Re: [OpenMap Users] map projection

The layer receives the MapBean's projection in the
projectionChanged(ProjectionEvent) method. The layer has a
setProjection(ProjectionEvent) method, and if you call that within the
projectionChanged() method, you can use the projection later by calling
getProjection().

After you modify the position of your OMGraphic, call
OMGraphic.generate(getProjection()), and then call layer.repaint().
