Thanks, I had already done that but without specifying "Include standard 
Zope persistent object base".

It's working now.

I am now trying to use the

WHEN OBJECT CHANGED STORE NOM, PRENOM, ID_ORG_ASS, NUM_OA,
DATE_NAISSANCE,
RUE1,
RUE2,
CODE_POSTAL,
VILLE,
TELEPHONE1 USING SQL_update(self)

clause.

I thought I could modify a dataskin attribute and that it would 
automatically save the new data.

When I try to modify an attribute with a python script

'''
patient = container.getItem(id)
patient.PRENOM = 'Gauthier'
return patient.index_html()
'''

in the specialist I get the error :

Error Type: TypeError
Error Value: attribute-less object (assign or del)

I think I did not understand correctly how the object and/or attributes is 
to be changed.

Hope some of you can help me. Thanks.
