[Zope] changing the meta_type for python product class

[Dragos Chirila]

Hi!

Thank you very much for your response.

Ok, you are right, but if I do it why the ZMI is showing to me the new
meta type for both instances? This is wrong...

Also, I don't understand why if I explicit change the meta_type
property for the old instance (e.g. a method of MyClass that is called
via URL) still nothing happens?

I also tried to add the following lines to the MyClass:

    _properties = (
        Folder._properties
        +
        (
            {'id': 'meta_type', 'type': 'string', 'mode': 'w'},
        )
    )

In the Properties tab for both instances the same value is shown for
the meta_type property.

Thank you very much once again for taking time to consider my problem.

Regards,
Dragos.
