[Zope-dev] ghosts of removed products haunting ZSQL Methods?

[John Ziniti]

I used to have the Product TrackerBase installed
and have removed it.  Now, however, attempts to
access the "Advanced" tab of ZSQL Methods is
broken because a chain of events attempt to get
info about a the non-existent Product:

lib/python/Shared/DC/ZRDB/dtml/advanced.dtml calls
manage_product_zclass_info

../ZRDB/DA.py.manage_product_zclass_info (line 546)
calls self.aq_acquire('_getProductRegistryData')('zclasses')

One of these items is the dict:
   "{'id': 'Tracker', 'meta_type': 'Tracker',
	'product': 'Tracker', 'meta_class': <ZClass instance at d55af0>}

Then, line 548 calls "if hasattr(z._zclass_,'_p_deactivate')".

The attempt to access z._zclass_ fails because this
product doesn't exist.

1) the call to z._zclass_ doesn't actuallt do anything
    except: ## Eek, persistent

2) Is this schizophrenic state my fault?

3) How to rectify the problem (Make *all* of Zope
    know that TrackerBase is gone)?


Thanks in advance, traceback follows,

Ziniti
