[ZPatterns] _v_dm_ KeyError calling get_transaction().abort()

[Itai Tavor]

Hi,

I have a method of a DataSkin object that looks something like this:

     def editMe(self, REQUEST, RESPONSE):
         """ Edit object for customer """
         ...
         ...
         if errors.has_any():
             get_transaction().abort()
             html = getattr(self, 'edit.html')(self, REQUEST, errors=errors)
             raise FormError, html


The html = getattr() line causes the following exception. If I remove 
the abort() line, this does not happen. Using Zope 2.3.2, ZPatterns 
0.4.3p2. I never had to abort transactions before, so I might be 
doing something bad... but I can't see what it might be. Any ideas?
