[Zope] python script returning DTMLMethod problem

Wed, 07 Aug 2002 20:03:41 +0200

hi tom,

have a look at http://www.zopelabs.com/cookbook/992031125 for the 
correct syntax calling a DTML-Method from a PythonScript.

must be something like this:

dtmlMethod(context, context.REQUEST)

or if _ is bound to the (Script) Python in the bindings tab

dtmlMethod(context, _)

I guess you need the last one [submitting the whole Namespace to your 
DTMLMethod]!

calling dtmlMethod(context) works only in some special cases, but it is 
not correct at all...

greetings, maik
