Bug in Archetypes constructor

I am writing an archetype based object. I need to give it a specific id.


So I write this:

     def __init__(self, id, **kwargs):
         BaseNewsletter.__init__(self, 'foldernewsletter', **kwargs)


When I try to add this type, I get an error. I have chased the bug down 
to the constructor call I have marked below:

     def _constructInstance(self, container, id, *args, **kw):
         """Build a bare instance of the appropriate type.

         Does not do any security checks.

         Returns the object without calling _finishConstruction().
         """
         m = self._getFactoryMethod(container, check_security=0)
         id = str(id)
         if getattr(aq_base(m), 'isDocTemp', 0):
             kw['id'] = id
             newid = m(m.aq_parent, self.REQUEST, *args, **kw)
         else:
             newid = m(id, *args, **kw) # ERROR ERROR ERROR ERROR
         # allow factory to munge ID
         newid = newid or id
         return container._getOb(newid)

It turns out that the newid returned::

     newid = m(id, *args, **kw)

newid == 'foldernewsletter'

is different from the one actually in the container. So when::

     container._getOb(newid) is called, it causes an attribute error.

actualid == 'foldersubscribeletter.2006-04-06.7196934836'

This must be a bug!

My "Product factory method" is called "addFolderSubscribeletter". This 
is not a real function I assume, but one that is created dynamically by AT.

My problem is that I cannot find where in the source to look for this. 
Would anybody give me a pointer to where/how the archetypes factory 
method is created, so that I can debug further?


Another thing... is there any way to overwrite the constructor in my 
content type, so I can work around the bug?
