[Zope] DTML Container?

[Alexandre Ratti]

Hello,


I think you can also render the body with: <dtml-var "_.render(this())">.

I know this looks kludgy, but it worked for me and you don't need to handle 
an external method. I included below a mail I sent when I came across this 
solution.


Cheers.

Alexandre
