[Zope-CMF] zpt skin weirdness

[Steve Arnold]

Howdy:

I'm still trying to wrap my brain around some of the basic zope stuff,
so maybe I shouldn't be messing with CMF (but I couldn't help myself ;)

I installed CMF 1.1 with the calendar stuff, then created a portal.  A
later updated to CMF 1.2 and created another portal instance.  This
second portal has the new ZPT-based skin as the default.  When I
modified the generic/standard_top_bar to add a calendar link to both
portals, it worked on the first one, but not on the second one.  That's
when I noticed that the ZPT skin in the second portal keeps it's basic
template files in another set of folders.  I found the nav_bar code in
the zpt_generic/main_template file and added my calendar link to the
top_bar.

However, and here's the weird part, when I click on the new calendar in
the top_bar of my portal site (with my default preference set to use the
ZPT skin) it displays the calendar, but it switches to the old basic
skin (ie, no more ZPT look and feel).  Then it switches back again when
I click on another link.  What the heck is going on?

I've been trying to figure this one out on my own, but I think I'm
stumped.  Anybody got any ideas?  There must be a few CMF gurus out
there...  Please?

Thanks in advance, Steve
