Hello,

...

After some digging, I found that the problem lies in the expression 'self.l'

'self.' gives access to the object hierarchy, not the variables namespace.

So, I solved my problem by writing 'self.REQUEST['l']' instead of 'self.l'

Also, I think that this should be clearly documented. Apparently, the only way to acess variables namespaces in external methods is through self.REQUEST This confuses a 'normal' python user whose variable namespace is usually accessed through self.

I believe that you can just ask for it in your function signature:

def my_method(self,l): return l + ' is cool!'

Nope, With that definition, my_method expect to be called with the arguments set, eg <!--#var "my_method('Zope')"--> to display "Zope is cool". However, I want to get the variable l from the namespace. (application variables made with REQUEST.set, Folder or document properties, etc.) The question was: is self.REQUEST the only way to access the variable namespace? And the only way to *modify* the variable namespace from external methods (with self.REQUEST.set)? By the way, I'd like to thank Stefan Franke and Pedro Vale Lima who gave me a pretty quick answer. I did find the answer before they wrote, but anyway, a thank is not that expensive :-) Also, thanks to Paul who gave me such a useless answer. :-) (just kidding) Regards, Jephte CLAIN Service Informatique CHSR
