[Zope3-Users] zpt pages though ZMI

Sun Sep 24 06:43:42 EDT 2006

Hello everyone,

Does anyone know the easiest way to let people (principals of a site) 
develop their own pages with no knowledge about zop3 structure? AFAIK 
The users need to make their own pages with HTML (more generally ZPT) 
and upload them as a ZPT page.

I dont want my whole website skin to disappear so I use the 
context/@@standard_macros/page for the zpt page.

when I add it, the page renders fine for the Manager(ZCML) but not for 
other principals, apparently the title for each principal can not be 
traversed.

this is my zpt page which I upload through the ZMI as Manager:

----------------------------------------------------------------------------------------------------------------------------
<html metal:use-macro="context/@@standard_macros/page">

</html>
----------------------------------------------------------------------------------------------------------------------------

and here is the error:
