[ZODB-Dev] Persistent unhashable?

[Christian Robottom Reis]

I'm trying to create a simple hash of persistent objects to other
persistent object. Something like:

class Foo(Persistence.Persistent):
 pass

class Bar(Persistence.Persistent):
 pass

f=Foo()
b=Bar()

a = {}
a.update( { f:b} )

raises an AttributeError: __hash__ error! Why?

Is this a known limitation of Persistent?

Take care,
