[Zope] cut and paste or an object

I have tracked the problem down to order of inheritance, but stull can't solve
it. My item class inherits from CatalogAware, then ObjectManager.
class Product(CatalogAware,Item,ObjectManager,RoleManager,ProductProperties):
CatalogAware has to be first so that manage_afterAdd, manage_afterClone and
manage_beforeDelete are over ridden so that the object can index and unindex
itself from the catalog. However, with CatalogAware being first, I get the
traceback below when pasting and object that has been cut.
If I inherit from ObjectManager first, then I can past without problem, but the
class is effectively no longer CatalogAware, and isn't indexed or unindexed
from my catalog.
I still cannot understand why absolute_url() is causing this error. I wrote a
small function on the object itself, which when called works perfectly.
def blah(self,REQUEST=None):
""" blah """
print self.absolute_url()
print self.url()
Why when absolute_url() is called from with the CatalogAware class does it
cause the error?
Has anybody else been able to paste CatalogAware objects? Can anyone help with
this...maybe somebody at digital creations?
