[Zope] A corker

[Bruce Eckel]

OK, I've figured this much out so far. I've created one
DTML document for each registration. I'm using acquisition
to pass that document to a DTML method that displays the
document. The URL looks like:
".../Yourfullname3b01efcd/DisplayFullRegInfo" where
Yourfullname3b01efcd is the document name, and
DisplayFullRegInfo is the DTML method.

Now I want to get the information in the document (which is
a python dictionary in text form) and use eval() (which
I've put in an external method) to parse it back into a
python dictionary. To get the data in the document, it
turns out all I have to do is say "PARENTS[0]". Now the fun
starts. This is in DisplayFullRegInfo:

<dtml-let data="PARENTS[0]">
<dtml-var data><hr>
<dtml-var expr="parseSeminarRegistration(data)">
</dtml-let>

I keep getting weird error messages for
parseSeminarRegistration(), which worked in a different
DTML method just fine. The messages complain about the
argument, so I decide to examine the argument type. Here's
the external method, parseSeminarRegistration():

import types
def parseSeminarRegistration(code):
  return 'your type is: ' + str(type(code))
  #return eval(code)

Normally I just use eval(), but this should indicate the
type. Here's the output:

 your type is: 


The external method is clearly called, but it simply gives
a blank. No 'None', even, as if *no* argument is being
passed (which I didn't think was possible).

I'm clearly missing something here. (If there's a more
appropriate way to get the data file then tell me to do
that).
