[Zope-PTK] Acquisition of properties?

Given the following folder tree:

/
XXX
YYY

Where XXX and YYY both contain property sheets with properties
defined, the "YYY" folder contains a "discuss" DTML method, and the
"XXX" folder is a PortalFolder and contains a "test" DTML Method
that reads something like:

<dtml-var standard_html_header>
<dtml-with YYY>
<dtml-var "discuss()">
</dtml-with>
<dtml-var standard_html_footer>

Why, when viewing "WWW/test", can't the "discuss" method find the
properties defined on YYY? I thought I understood acquisition...

Aaargh. That should be "XXX/test" of course. Same question holds
tho.

It's because you've lost your namespace. If you do,

<dtml-var standard_html_header>
<dtml-with YYY>
<dtml-var discuss>
</dtml-with>
<dtml-var standard_html_footer>

you should get what you want. Or,
<dtml-var "discuss(_.None, _)">

<dtml-var discuss> is equivalent to <dtml-var name=discuss>. When called
that way, a DTML method is automatically given the namespace. <dtml-var
expr="discuss(_.None, _)"> would be the syntax to make sure that the
namespace is passed in to the DTML method when calling as an expression.
