[mapguide-users] Unable to select polygon?!?

[Kori Maleski]

Ivan,

When I view the Polygons in Autocad Map - there is a an issue with the left
polygon:

It is not 'closed' properly.  When you select the right polygon it is
entirely highlighted.  When you select the left polygon, the left boundary
segement does not highlight (since it is not there).

You may have to add the starting coordinate to close it:

coords.Add(geometryFactory.CreateCoordinateXY(x - 50, y + 50));
coords.Add(geometryFactory.CreateCoordinateXY(x + 50, y + 50));
coords.Add(geometryFactory.CreateCoordinateXY(x + 50, y - 50));
coords.Add(geometryFactory.CreateCoordinateXY(x - 50, y - 50));
coords.Add(geometryFactory.CreateCoordinateXY(x - 50, y + 50));

Cheers,
