Dylan, Most definitely ! Here's the relevant code: from Globals import Persistent, DTMLFile, InitializeClass from AccessControl.Role import RoleManager from AccessControl import ClassSecurityInfo from Acquisition import Implicit from OFS import SimpleItem from ogclib.WFS import GETQuery <--- My python module def addWFSGETQuery(self, id, connection, typename, title='', propertyname='', featureversion='', maxfeatures='', featureid='', filter='', bbox='', REQUEST=None): """ Add a WFS GET Query object """ self._setObject( id, WFSGETQuery(id, connection, typename, title, propertyname, featureversion, maxfeatures, featureid, filter, bbox ) ) if REQUEST is not None: REQUEST['RESPONSE'].redirect(self.absolute_url()+'/manage_main') class WFSGETQuery( GETQuery, SimpleItem.Item, Persistent, Implicit, RoleManager ): <- The Zope wrapper for my module def __init__( self, id, connection, typename, title='', propertyname='', featureversion='', maxfeatures='', featureid='', filter='', bbox='' ): self.id = id self.edit( connection, typename, title, propertyname, featureversion, maxfeatures, featureid, filter, bbox ) security.declareProtected( 'Change Database Methods' , 'edit' ) def edit(self, connection, typename, title='', propertyname='', featureversion='', maxfeatures='', featureid='', filter='', bbox='' ): self.connection = connection self.typename = typename self.title = title self.propertyname = propertyname self.featureversion = featureversion self.maxfeatures = maxfeatures self.featureid = featureid self.filter = filter self.bbox = bbox self._cleanupparams() <--- provided by GETQuery # Get feature type information and validate self._getfeaturetypeinfo() <--- Provided by GETQuery The problem is that outside of zope "connection" is an instance of another class ("Connection") ... _getfeatureinfo() which is called by edit which is called by __init__ needs that instance in order to do some work. But I can't get that instance because getattr doesn't find it !! (Even though it is there, in the same folder, available to be acquired) The strange thing is that before I wrote the classes into python modules, I had the whole thing as pure Zope products, and everythng was working fine. then I split it into two in order to have the functionality as regular Python modules, and when I come back into Zope, the same thing no longer works ?

The problem is the second one, which uses the first one. First of all, it looks like while the class is being instanciated, there isn't any acquisition yet ?

Did you use the Acquisition.Implicit mixin when you defined the class? HTH, Dylan
