RE: [Jython-users] Emulating Jython object attribute access with a Java class

If you change your Java class not to extend PyObject,
then your examples work.

Subject: Re: [Jython-users] Emulating Jython object attribute access
with a Java class


So I guess it is not recommended to provide Jython object attribute 
access with a Java in the way suggested by the FAQ (maybe it should be 
mentioned in the FAQ).
Is there any better way to do it?
More generally which kind of jython functionalities a java class can 
safely implement ?
I think of all the methods that are mentioned in several books and 
e-mails (__finditem__ etc& etc&)
Is there any official commitment about them ?

Thanks in advance

Nicola
