There must be some BUG in API, here is my code:
var p2:Polygon =
polygons.getCountryData("FIN").getPolygon(); //
Get polygon from encoded data
_map.addOverlay(p2);
if (p2.getInnerPolylineCount() > 0) { // If is polygon
created from
many polylines
for (var lIdx:int = 0; lIdx <
p2.getInnerPolylineCount(); lIdx++)
{ // Get polylines count
for(var ivIdx:int = 0; ivIdx <
p2.getInnerVertexCount(lIdx); ivIdx
++) { // Get vertex count for each polyline
polygonsBounds.extend(p2.getInnerVertex(lIdx, ivIdx)); // CRASH
ON ERROR
}
}
}
else {
for (var ovIdx:int = 0; ovIdx <
p2.getOuterVertexCount(); ovIdx++)
{ // Get outer vertex count
polygonsBounds.extend(p2.getOuterVertex(ovIdx)); // Get current
vertex
}
}
When I run this code for polygon which is created from some inner
polylines, it crashes on p2.getInnerVertex(lIdx, ivIdx) with this
exception:
ReferenceError: Error #1069: Property copy not found on
com.google.maps.LatLng and there is no default value.
at com.google.maps.overlays::Polygon/getInnerVertex()
at com.google.maps.wrappers::IPolygonWrapper/getInnerVertex()
So I really don't understand what's going wrong :(
