problems with maya python api 1.0 MPxGeometryIterator -

i'm writing custom curve maya python api 1.0 , got stuck mpxgeometryiterator:

//error: line 1: typeerror: file ..\maya\openmayampx.py line 1092: in method 'mpxgeometryiterator_isdone', argument 1 of type 'mpxgeometryiterator const*' //

inside shape call iterator:

def geometryiteratorsetup(self, componentlist, components, forreadonly = false):     if components.isnull():          result = asmi.autosplinemovableiterator(self, componentlist)     else:         result = asmi.autosplinemovableiterator(self, components)     return result 

this have far iterator, maya crashes gets called

class autosplinemovableiterator(openmayampx.mpxgeometryiterator):     def __init__(self, usergeometry, components):         super(autosplinemovableiterator, self).__init__(usergeometry, components)          self.geometry = usergeometry         self.reset()  def reset(self):     openmayampx.mpxgeometryiterator.reset(self)     self.currentpoint = 0     if self.geometry:         maxvertex = self.geometry.pointcount()         self.maxpoints = maxvertex  def point(self):     pnt = openmaya.mpoint()     if self.geometry:         pnt = self.geometry.point(self.index())     return pnt  def setpoint(self, pnt):     if self.geometry:         self.geometry.setpoint(self.index(), pnt)  def iteratorcount(self):     if self.geometry:         return self.geometry.pointcount()     return 0  def haspoints(self):     return true 

i'm not quite sure i'm doing wrong. passing wrong arguments?
