[Zope] Here's how to call a method with a known location from anywhere in the site tree.

[Sungmook Kim]

yep, it's a method.
but within the folder guestbook, i call this method
as <dtml-var addEntryAction> and it works.
whereas the addEntryAction calls
<dtml-call expr="addEntry(arg1, arg2,...)">

i thought this should work in another folder
X too by writing
<dtml-var
"PARENTS[-1].GuestBook.addEntry(arg1,arg2,...)">

should it not?
