[Zope3-Users] zpt pages though ZMI

Mon Sep 25 01:33:30 EDT 2006

Thanks Darryl

you were right about the title attribute of unauthenticated principals. 
they don't have it.
I made another ZCML principal with a title and it works fine.

The problem still remains the same though for the principals in the PAU. 
I always thought they do have a "title" bacause it is shown on "ordinary 
pages" when you login. ( well unauthenticated principals also show up :) )

I checked it with Boston skin. The principal title gets rendered but 
there is again another problem with some "econtext.view" that messes 
everything up again. I will try to figure that out or just borrow the 
request/principal/title part from boston skin and hang with my own skin 
which I like better.

Thanks again
