OK, I tried this:

myResult_if_any = DTMLMethod.DTMLMethod.__call__(self.myMethod, REQUEST=REQUEST)

But; I'm still getting the error "NameError: Error Value: global name 'REQUEST'

The method I'm calling is contained by self, which is a folderish object.

I'm making this call from one of the methods of the product class that self is an instance of.

Any further thoughts?

Thanks again

Yes, I have a number of such calls in the DTMLMethod I'm attempting to call from the python product.

i understand, that you call a DTMLMethod, which contains these calls

I know this must seem like a dumb question; but can you tell me how to pass an empty REQUEST object in the call, so the DTMLMethod can set and make use of these variables?

__call__(myDTMLMethod, REQUEST???)

from the top of my head myResult_if_any = myDTMLMethod(self, REQUEST=REQUEST) or myResult_if_any = myDTMLMethod(self)

This effects a "binding" of the REQUEST object (right hand side) to a parameter named REQUEST (in the second case default = {}

...

...

a) REQUEST is an object that seemingly behaves just like a python dictionary b) the __call__-method of DTMLMethod has REQUEST={}, so by default if no 2nd parameter is given, it is empty. Note that DTMLMethods are usually interpreted in the context (=namespace) of their caller.

= client

...

c) the third parameter **kw is a sequence of keyword parameters.

So does that mean I need to pass an empty dictionary as the second parameter to _call_ so that my DTMLMethod will have a REQUEST object that it can start filling with variables using <dtml-call "REQUEST.set( 'yourname', yourvalue)"> ?

Could you provide the exact syntax I need to use in _call_ ? Whatever I try, I always get the error "global name 'REQUEST' is not defined"?

Presumably because the DTMLMethod I'm calling is trying to set variables in a REQUEST object; but it's not getting one, and I still don't understand how to provide this. I'll also need to provide some other variables to the DTMLMethod. I guess I need to use **kw for that? Again the exact syntax I need to use, by example, would be appreciated.

The end of the traceback is as following:

(Object: REQUEST.set('newsMgr', id)) (Info : REQUEST) File <string>, line 2, in f NameError: (see above)
