[Zope] Can't compare apples to apples. (document_id != id_of_my_document)

[T.J. Mannos]

Hi, there,

I have a DTML document called "apples".

A call to <dtml-var document_id> gives the string "apples"

However, a <dtml-if "document_id == 'apples'"> returns false.  Am I missing
something?  I've tried _.str(document_id) and even
_.string.strip(_.str(document_id)).

Thanks,
T.J.
