You can't use a class object as a function... in this case, you're defining the function name in the external method as "mp3info", which is a class, which is why you're getting this error. I don't see any functions at all in the file you posted. An external method wraps a Python function. Passing instances of classes defined in an external method is tricky as well, even if you are using a function. It seems like you really want to be building a Product. See the Zope Developer's Guide at http://www.zope.org/Documentation/ZDG for information on how to do this. - C ----- Original Message ----- From: "marc lindahl" <marc@bowery.com> To: "Tino Wildenhain" <tino@wildenhain.de>; <zope@zope.org> Sent: Monday, April 30, 2001 9:24 PM Subject: Re: [Zope] problem with External Methods
OK, I put it here, for now (it's not done, yet):

Hi marc,
it would be more helpful if you provide your external methods code also :)

on 2.3.2 I just tried to add an External Method and got this error -- anyone have an idea? Seems like some stuff in ExternalMethod.py isn't getting initialized (for example, if I initialize func_defaults in the .py I'm trying to externalize, it gives another error, about func_code). Is there requirements of the .py, something that needs to be imported or whatever, for this product to work?
