[Zope] Lost in name Space...

[Pierre-Julien Grizel]

You can try

<dtml-with "RandomGreeting">
	<dtml-var Greet>
</dtml-with>


Think of the namespace as a stack : whenever you address an object using
the dot notation as you did, you do not put the RandomGreeting folder in
the stack.
When you use the <dtml-with> tag, you just put RandomGreeting up the
stack.

Namespace stack with the dot notation :

-----------
|  Greet  |  (Remember a DTML Method applies to its calling folder !)
-----------
|    /    |
-----------


Namespace stack with <dtml-with> :

-------------------
|      Greet      | 
------------------|
|  RandomGreeting | 
------------------|
|        /        |
-------------------



That's it !
