It looks like there is a bug in how the properties are being
initialized in MultiShapeLayer. The line (130):

        setSpatialIndexes(realPrefix, props);

should be:

        setSpatialIndexes(prefix, props);

realPrefix is "", which is getting translated into "." in
setSpatialIndexes(). If you add some marker name string to the
properties above, that would work, too:

        shapeLayerProps.put("usa_view.prettyName", "USA View");

appending "usa_view." to all property names, and then calling:

        usa_view.setProperties("usa_view", shapeLayerProps);

below. Note that usa_view (your object name) is unrelated to
"usa_view" (the property scoping name).

Also, you need to further scope these properties below so they can be
given to the proper SpatialIndex

                 shapeLayerProps.put("world.lineColor", "000000");
                   shapeLayerProps.put("world.fillColor", "FFFFFF");
                   shapeLayerProps.put("world.shapeFile",
"C:/openmap-4.6/EgoMap/ESGData/world.shp");
                 shapeLayerProps.put("world.enabled", "true"); 
                   shapeLayerProps.put("usa.lineColor", "000000");
                   shapeLayerProps.put("usa.fillColor", "FFFFFF");
                   shapeLayerProps.put("usa.shapeFile",
"C:/openmap-4.6/EgoMap/ESGData/usa.shp");
                 shapeLayerProps.put("usa.enabled", "true");

I put "usa." or "world." in front of each property as appropriate. You
would add "usa_view." in front too if you start adding that to all the
properties.

I've fixed the bug for the next release.

Don
