[z3-five] SimpleViewClass and __hash__

[Tarek Ziadé]

Hi,

I've ran into some problems with CPSSkins under CPS3 and a Product using 
Five.

CPSSkins creates a persistent dictionnary wich keys are zope 2 methods 
names (zpt, py, dtml, etc)

It raises errors on pages templates created through Five because they do 
not have a __hash__ method
for the dict to work properly.

I would like to suggest a change in 
pagetemplatefile.ZopeTwoPageTemplateFile by adding a hash method :

    def __hash__(self):
        return hash(self._cook)

then in browserconfigure, adding a method :

def __hash__(self):
    return hash(self.index)

that's binded in makeClassForTemplate to class_ =

class_.__hash__ = __hash__


That would make page templates usable as dictionnary keys in Zope 2.

Cheers

Tarek
