First of all I'd like to thank you for all your help. I've strugling
with this for almost a  week.


What I'm trying to do:

Directory structure Products/SearchObject/__init__.py
					 /SearchObject.pt

File __init__.py

__doc__ = """ Search Object Product """
__version__ = '0.1'

import SearchObject

def initialize(context):
	"""Initialize the Search Object product
        This makes de product appear on the product list"""
	global SearchObject
        import SearchObject
	context.registerClass(
                SearchObject.SearchObject,
                constructors = (
                        SearchObject.manage_prevAddSearchObject,
                        SearchObject.manage_addSearchObjectForm,
                        SearchObject.manage_addSearchObject),
	)



File SearchObject.py:

manage_addSearchObjectForm = DTMLFile('dtml/searchObjectManage',
globals())

def manage_prevAddSearchObject(self):
        "Criacao de um objecto SearchObject"

#	print 'Ola' + str(self)     
#	global manage_addSearchObjectForm  ##### Desperate attempt #####
#	import SearchObject		    ##### Another one #####
        return manage_addSearchObjectForm() ##### Error in this line.
#####

def manage_addSearchObject(self,
...


In some words I want to make some computation before calling the DTML
form.

Error Type: AttributeError
Error Value: aq_parent

File
/home/anjc/Zope-2.3.0-linux2-x86/lib/python/Shared/DC/Scripts/Bindings.py,
line 290, in _getContext
    (Object: searchObjectManage)
AttributeError: (see above)

I don't think this is the case.
