[Zope] Re: tree elsewhere...

[Darcy Clark]

Ethan,

thanks for the mail. Methods and documents are becoming clearer...but at
the same time I keep finding that I almost want to be able to switch
modes within the same page. So for some parts of a page/layout (whatever
you want to call it), I want it to act as a 'pseudopod of a folder', and
then later on, (for instance to get standard_html_header to work like I
want) I want the same page/layout to work in the document 'mode'.
Manipulating namespaces and contexts is currently not a trivial matter
which I am frankly finding very confusing (yet powerful at the same time).

cheers,

Darcy
