[Zope] External method woes Zope 2.5.1 - no parameters being passed into external method - works fine with a refresh

[Sean McGrath]

I download a fresh Zope 2.5.1 for Windows.

I create an external method "foo".

def foo (self, REQUEST, RESPONSE):
	return "Hello World."

I register it with id "foo".

First invocation of /foo gives me:

	Error Type: TypeError
	Error Value: foo() takes exactly 3 arguments (0 given)

I hit refresh and all is well!

Occasionally but unpredictably, the problem
re-occurs but disappears again for a while when I hit refresh.

Browser is IE 6.

Does this scenario ring any bells with anyone?

regards,
Sean
