Re: Reference to the MapBean

Hi Cicero,

The EditableOMGraphic objects were intended to be used with the
OMDrawingTool, so I'm not sure how they act if the OMDrawingTool isn't
involved. You can look at that class to see how it sets up the
EditableOMRangeRing, though, and that may help.

In general, though, if you want to repaint a graphic that is part of a
layer, you call repaint() on the layer. You also can get a reference
to the MapBean via the ProjectionEvent that comes to the layer in the
projectionChanged() method, as the source of the event.

Hope this helps,

Don
