[Zope] Answer about REQUEST problems in 2.1.6 ZSQL Methods...

28 Apr 2000

      For those of you who have been struggling to figure out why 
references to REQUEST (like <dtml-with REQUEST>) don't seem
to be working anymore on 2.1.6 installations, I think I've 
finally tracked it down.

In lib/python/ZPublisher/BaseRequest.py, there is a section 
near the top:

try:
    from ExtensionClass import Base
    __roles__=None
    class RequestContainer(Base):

        def __init__(self,**kw):
            for k,v in kw.items(): self.__dict__[k]=v

        def manage_property_types(self):
            return type_converters.keys()

Note that the __roles__=None line is in a silly place - it really
wants to be in the class statement:

try:
    from ExtensionClass import Base

    class RequestContainer(Base):
        __roles__=None        
        def __init__(self,**kw):
            for k,v in kw.items(): self.__dict__[k]=v

        def manage_property_types(self):
            return type_converters.keys()

Note that this fix will be in the next release - in the meantime
you want to make this fix to your BaseRequest.py file in your
2.1.6 installation rather than work around it by changing DTML
code to pass the REQUEST explicitly.
