[Zope] Newbie Q:<dtml-with> and the PARENTS tag

[List Subscriptions]

Thanks very much for the suggestion, but Method1 needs to be a 
method; if it's a document, some of the other methods it calls 
fail to function properly.

In addition, though what you say makes sense to me, it doesn't 
seem to work that way in practice.  I placed the code in DTML 
Doc and observed the same behavior:  PropertyX (actually, 
another DTML Doc) was picked up from higher up in the hierarchy, 
even with the 'only' parameter.  Also, as I noted, <dtml-var 
"PARENTS[0].id"> DOES pick up the proper container (perhaps b/c 
I already have other items in the folder, perhaps, but it does 
show that it's working with the right object).

If you (or anyone else on the list) has more suggestions, I'm 
all ears.  Again, I don't really care how it's done, I just want 
the basic logic to work.  Are there any other acquisition 
keywords I could use?
