Bruno Chareyre proposed the following answer:
Hi Reza,

Your compilation problem is because you are not simply trying to pass an
argument. The syntax you are using is for registering an attribute (*),
which is more demanding in terms of object type (it has to inherit from
serializable).
It should be possible to achieve what you want by passing arguments, as
shown by Christian. The main bad side is that the template list will be
lost if you save the simulation and reload it latter. If it is really a
problem, you can probably register standard vectors to handle the data,
in the form below:

class Factory {
void setTemplates(python::list templates) {//convert templates into
lists of Vector3r and Real registered below }
YADE_CLASS_...
((vector<vector<Vector3r> >, positions, ...))
((vector<vector<Real> >, radii, ...))
}

HTH

Bruno
