Hi,
Thanks Max, but it seems to work only if the base class is a "root" =
class (does not inherit of an other one).
In my case, I have...
<SNIP>
from UserList import UserList
class Myclass(UserList):
def __init__(self, data=3D[]):
...
# Exception raises from here now!!!
UserList.__init__(self, data)
...
class ZMyClass(SimpleItem, MyClass):
...
def __init__(self, id, title=3D''):
...
ZMyClass.inheritedAttribute('__init__')(self)
...
</SNIP>
I could rework my code to have...
class ZMyClass(SimpleItem, MyClass, UserList):
...
But in that case (multiple __init__ due to multiple inheritance) WHERE =
does the inheritedAttribute finds the method.
Is there some doc for Python product programmers where I could find =
other APIs guides ?
There's - approximately - nothing for this in the Zope book.
I did not find anything and hack other's code doing things other do =
whithout knowing why.
In example, I did not find the difference between initializeClass and =
initializeBaseClass.
Thanks again.

: As far as I remember you should:
:=20
: class myObject(ObjectManager) =20
: =20
: def __init__(self, id):
: "Inits the object"
: myObject.inheritedAttribute('__init__')(self, id)
:=20
: Anyhoo you can google on "inheritedAttribute" and stuff should show =
up.
