[Bf-python] Scripting error or bur in API ?

[Patrice Ferlet]

Hello

I am using Blender 2.28a, and trying to duplicate object in python script.

I get an object, named "objSrc" which is a mesh.

I create  a new mesh and use shareFrom method:

mymesh=Blender.Object.New('Mesh',"test_mesh")
mymesh.shareFrom(objSrc)

Here is the python output:
In Object_GetSelected()
[Object "Cube"]
Traceback (most recent call last):
  File "Text", line 12, in ?
TypeError: argument 1 is not of type 'Object'

So, i try to remove the "new" method and i have:
In Object_GetSelected()
[Object "Cube"]
Traceback (most recent call last):
  File "Text", line 12, in ?
AttributeError: type object 'object' has no attribute 'shareFrom'

Where is the problem ?
