[Zope] simple DTML question ...

[Darran Edmundson]

It's 12:30 am and I've been Zoping for 15 hours without
a break.  I just ran into a problem that can be pared
down to the following example ...

Create a DTML method:

  <dtml-var standard_html_header>
  <dtml-var "foobar(year='chosen_year')">
  <dtml-var standard_html_footer>

and try to render it where foobar is another DTML method:

  <input type=text name="<dtml-var year>:int"
     value='<dtml-var "ZopeTime()" fmt="%Y">'>

I suspect the source of my misunderstanding can be put
in an even simpler example.  If foobar contains only
<dtml-var "ZopeTime()"> then calling foobar via
<dtml-var "foobar"> returns the unevaluated DTML.  Why
is this?  I wandered through Amos' "Advanced DTML"
How-To but I'm not thinking clearly.  I can probably
figure it out tomorrow but I would dearly love to awake
in the morning and find the source of my confusion
awaiting in my Inbox.

Cheers,
darran.
