I have an external python function, who's header starts like this:

def Toggle(self, var='a', optvar=None,trueval=None, falseval=None, REQUEST=None,RESPONSE=None): "Toggle Test based on cookies and URL"

I call it from dhtml, like this:

<!--#call "Toggle(var='TogA',optvar='rowcount',trueval=99,falseval=5, REQUEST=REQUEST,RESPONSE=RESPONSE)"-->

If I don't use REQUEST=REQUEST,RESPONSE=RESPONSE

I get read-only buffer, class exception.

Is this the way it's expected to function?

I can also call this function as

<!--#if "Toggle(var='TogA', REQUEST=REQUEST,RESPONSE=RESPONSE)"-->

Same deal, must have REQUEST.

Is there any way I can avoid explicitely passing REQUEST and RESPONSE?

If you dont use REQUEST or RESPONSE in the method, then you dont have to pass it in. If you use them though, then they need to be passed in like any other argument. Brian Lloyd brian@digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com
