MeshPoint not having edgeIndex

Scripting

When using closestMeshPoint the meshpoint have the faceIndex and T but no edge info

import Rhino
import Rhino.Geometry.Point3f as Point3f
import scriptcontext

mesh = Rhino.Geometry.Mesh()
mesh.Vertices.Add(Point3f(0,0,0))
mesh.Vertices.Add(Point3f(1,0,0))
mesh.Vertices.Add(Point3f(0,1,0))
mesh.Vertices.Add(Point3f(0,0,1))


mesh.Faces.AddFace(0, 1, 2)

mesh.Faces.AddFace(3, 1, 0)
mesh.Faces.AddFace(3, 2, 1)
mesh.Faces.AddFace(3, 0, 2)
mesh.Compact()

p = Point3f(1,1,0)

mp = mesh.ClosestMeshPoint(p, 1000000000.0)
print mp.GetTriangle()
print mp.EdgeIndex
print mp.T
print mp.FaceIndex
print mp.EdgeParameter

scriptcontext.doc.Objects.AddMesh(mesh)
scriptcontext.doc.Views.Redraw()

This gives the result

(False, -1, -1, -1)
-1
Array[float]((0.0, 0.5, 0.5, 0.0))
2
0.5

Which clearly stats that if found the face, and that it is on a edge but not what edge. Am I missing a Compact call?
If any one knows how to get the id of the edge of just the id of the face on the other side of the edge then I would be greadfull.

Rhino.Geometry.Mesh.ClosestMeshPoint does not calculate Rhino.Geometry.MeshPoint.EdgeIndex. But with the result, you should be able to calcualte the closest edge yourself.
