[ZPatterns] bug using ZedPatterns with Zope 2.5

[Steve Alexander]

Hi Folks,

There's a bug with using ZedPatterns with Zope 2.5.

The fix is simple. Apply this patch to ZPatterns/Expressions.py.



*** Expressions.py.original
--- Expressions.py
***************
*** 50,56 ****
         stack._push(InstanceDict(object,stack))"""

       # Called by Zope only
!     def validate(self, inst, parent, name, value, md):
           return getSecurityManager().validate(inst, parent, name, value)


--- 50,56 ----
         stack._push(InstanceDict(object,stack))"""

       # Called by Zope only
!     def validate(self, inst, parent, name, value, md=None):
           return getSecurityManager().validate(inst, parent, name, value)


The annoying thing is that I fixed this bug in the Zope core for Zope 
2.5a1. I didn't think to check ZPatterns for the same bug! Doh!
