Hi, yes there is a DBNull value. Thanks.

DBNull is a singleton and I’d guess we’d need to add some custom logic which says the way we deserialize it is by pulling the singleton from DBNull.Value. You can probably use copy_reg.pickle to register something which will handle objects of type DBNull that just returns DBNull.Value.

I moved the copy module from the IronPython 2.6 installation to work with IronPython 2.0 for some compatibility problem I had with IronPython 2.6 dll with another dll we use. The only difference I see between the cases which works and those which doesnt are, in the succesful case it is a custom class object "alone", and in the error case is the deepcopy of a custom class object which contains a list with other instances of that object. Could that have anything to do with the problem? Is that a limitation of the copy module in Python or it should work? error description: No se puede encontrar el método 'DBNull..ctor'.
