Re: Need help with GPolyline

The map click handler passes two arguments, but only one of them will
be non-null.

If you click on a marker, 'overlay' is a GMarker object and 'point' is
null.
If you click on the bare map, 'overlay is null and 'point' is a GPoint
object.

The GPolyine constructor takes one more argument for opacity, but I
think it should default.

Please post a link if this doesn't lead to a solution.
