[TransWarp] Is there a problem with module Inheritance ??

[Ulrich Eck]

Hi Philip,

i followed your example to use a specialist and found out the following:

when i code as you suggested in your first mail from 18.03.2002:

MyDomainLayer.py:
---------------------------------------------------------------------------
from TW.API import *

class User(SEF.Element):

	class dn(SEF.Field):
		pass
		
	class cn(SEF.Field):
		pass
		
class Users(SEF.Specialist):

	def dosomething(self,text):
		print "i do: " +  text

setupModule()
---------------------------------------------------------------------------

MyDispatchLayer.py
---------------------------------------------------------------------------
from TW.API import *

import MyDomainLayer
__bases__ = MyDomainLayer,

class User:

	class dn:
		pass
		
	class cn:
		pass
		

class Users:
	
	elementClass = User
	recordManager = SEF.bindTo('MyDatabase.Accounts')
	requiredType = 'PosixAccount'
	keyField = 'uid'


setupModule()
---------------------------------------------------------------------------

i get the following error when i use it:

...
  File "/usr/lib/python2.2/site-packages/TW/SEF/Basic.py", line 459, in 
__getitem__
    item = self._retrieveItem(key)
  File "/usr/lib/python2.2/site-packages/TW/SEF/Basic.py", line 521, in 
_retrieveItem
    return self._wrapElement(record)
  File "/usr/lib/python2.2/site-packages/TW/SEF/Basic.py", line 530, in 
_wrapElement
    element._setSEFparent(self)
AttributeError: User instance has no attribute '_setSEFparent'

when I put

	elementClass = User

into MyDomainLayer and remove it from MyDispatchLayer everything works fine.

shouldn't the rebuilt classes be replaced by name in all modules ???

or did i just get something wrong with module-inheritance ??
