[Zope] Re: passing context using expr="dtml_method()"?

[John Withers]

Maik,

Thanks for your help. I had actually seen the section of the book you 
referenced and was trying to pass it as :
<dtml-var expr="mymethod(_)">

instead of passing it as
<dtml-var expr="mymethod(None, _)"> or
<dtrml-var expr="mymethod(callingDoc)">.

Thanks for your help in pointing me back to this section and understanding it.
