So this *should* work (see below). Its what I'm using, it lives in my
Layer class. When a line is added that layer disappears. resizing the
window makes it come back with the added line.

TIA

public void setLine(LatLonPoint a, LatLonPoint b)
{
    System.out.println("adding line "+
        +a.getLatitude()+","
        +a.getLongitude() + " "
        +b.getLatitude() + ","
        +b.getLongitude());



    OMLine l = new OMLine(
        a.getLatitude(),
        a.getLongitude(),
        b.getLatitude(),
        b.getLongitude(),

        com.bbn.openmap.omGraphics.geom.BasicGeometry.LINETYPE_STRAIGHT
        );


    graphics.add( l);

    graphics.generate( getProjection(), true);


    repaint();

    System.out.println(graphics.size());

} // setLine



have fun,
