ok. typo by me.

Is it a DTML Method or DTML Document?
I'm positivly sure that you have to pass something. But it could be awefully
complicated what and when and why.
Experts!? Help.

I was working on a Python Script, and I remember that somedtmlobject() never
worked but finally did later when I passed context and REQUEST. In mycase it
was just a call, and I wasn't interested in what it returned.

'excessive recursion error' is good. That means that your Python Script
"DTMLcalling" works. It's just a matter of if it returns HTML or text.
The excessive recurssion is because you're calling an object that calls the
script.
Do it with context.bloodyjavascript() or something instead.
