CAWeightTag.TransferWeightMap Hows it work?

I am trying to utilize CAWeightTag.TransferWeightMap in my python plugin, and I can't tell if it isn't working or if I am just doing something stupid.
Here's my line of code:
wt.TransferWeightMap(self.doc, wt, sourceID, targID, 0, pointCount)
So wt, is my weight tag, self.doc is basically doc, sourceID and targID are ID's I obtained by doing wt.FindJoint.
This is within a loop that goes through and tries to copy weight maps from the source joint to the target.
It runs without any errors, so I don't know what I am doing wrong here. I also tried using c4d.NOTOK for the last two arguments. the SDK isn't very clear on how to use this, or if this will even work the way I am thinking.
I've also tried not using wt as an argument, and instead creating a new weight tag and adding joints in there, but am having no luck.
Could anyone shed some light on how this is supposed to work and/or maybe present an example file? Your help would be greatly appreciated.

it appears that there are a few issues with TransferWeightMap() in the Python API. So I'm afraid this function is currently not usable. You may have to go a little bit more low level and copy the weights manually using GetWeight()/SetWeight().
# loop through all points pointCount = polyObject.GetPointCount() for pointIndex in xrange(pointCount) : weight = weightTag.GetWeight(jointIndex, pointIndex) print("Point: " + str(pointIndex) + " : " + str(weight))

Thats what I was afraid of.
Going point by point to set weights across many joints to transfer maps from one to another is very slow and inefficient.
That is too bad. I guess I will continue to try and work thru learning c++ so it can be faster.
