[Zope] [Skinscript] unable to update property

[Dirksen]

Hi Steve,

I ran into a very tricky problem when developing a site with emarket. Here is the
structure of my site:

root
 |--acl_users(Membership product)
 |--emarket
     |--shoppers

The acl_users is an instance of Membership product, which is as a specialist as shoppers,
and they both have a WebIC_MemberClass zclass as their rack object class. The difference
is that, acl_users stores WebIC_MemberClass persistently, while shoppers just reflects
that storage. Here is the skinscript for shopper's rack:

WITH acl_users.getItem(self.id) COMPUTE
     oo=RESULT

WITH self.oo COMPUTE
     email,
     transCount

WHEN OBJECT CHANGED STORE transCount USING 
     self.oo.propertysheets.webic.manage_changeProperties(transCount=self.transCount)

When emarket trying to increment a shopper's transCount, I ran into a
"ZODB.POSException.ConflictError". The following is the traceback:
Traceback (innermost last):

ConflictError: ('\0039\323C4=\266\210', '\0039\323B\375\036\270U')

Is it something wrong with my skinscript?

cheers
