I'm having some trouble with calling External Methods from DTML documents. I have DTML document "Query" that defines a form with action "View". "View" is also a DTML document containing a call to an External Method: <!--#var ExtMethod -->

Ext Method would like to get access to the form values passed to View, but I can't figure out how to do it. There doesn't seem to be a way for ExtMethod to acquire the values and I can't pass them as arguments.

Try passing in the REQUEST mapping:

in DTML:

<!--#var "ExtMethod(REQUEST=REQUEST)"-->

in Python:

def ExtMethod(self, REQUEST): fv1 = REQUEST['form_var1'] fv2 = REQUEST['form_var2']

This what your looking for?
