Zope and Frames (was Re: [Zope] ZPT and CSS)

[Andre Meyer]

Hi again

As Tino says, this is not about frames per se, but in a <frameset> you
need to specify the framed pages. Therefore you need a reference and
that should be done in the __init__.py.
Or is there another possibility? Of course, the need to specify all
references to pages and images in __init__.py is not convenient,
particularly when you already have a database and need to recreate an
instance of your product. (btw this applies to a filesystem-based
approach).

========================================================================
Here is what I have in my __init__.py:

__doc__ = """Music Library initialisation module"""
__version__ = '0.1'

import mlib
import Piece
import Composer
from ImageFile import ImageFile
from Products.PageTemplates.PageTemplateFile import PageTemplateFile

misc_ = {
	'mlib.css':ImageFile('zpt/mlib.css', globals()),
	'mlibPrint.css':ImageFile('zpt/mlibPrint.css', globals()),
	'index_top':ImageFile('zpt/index_top.zpt', globals()),
	'index_bottom':PageTemplateFile('zpt/index_bottom', globals()),
	}

def initialize(context):
...
========================================================================
http://localhost:8080/music/misc_/mlib/index_top
This returns the zpt page unprocessed.
========================================================================
http://localhost:8080/music/misc_/mlib/index_bottom
This zpt page can be rendered without problems in the usual way (linked
from another zpt page), but when accessed as above it returns the
following error page:

Site Error

exceptions.AttributeError

Sorry, a site error occurred.

Troubleshooting Suggestions

      * The URL may be incorrect.
      * The parameters passed to this resource may be incorrect.
      * A resource that this resource relies on may be encountering an
        error.
For more detailed information about the error, please refer to the error
log. 

If the error persists please contact the site maintainer. Thank you for
your patience. 


Additionally, in the console the following error is shown:

2003-12-04T08:41:03 PROBLEM(100) Zope Security Policy
'<ComputedAttribute object at 0x85db148>' passed as roles during
validation of 'index_bottom' is not a sequence.

Any help is appreciated.
kind regards
