Update of /cvs-repository/Zope3/src/zope/app/broken
In directory cvs.zope.org:/tmp/cvs-serv4961/src/zope/app/broken

Added Files:
	__init__.py broken.gif broken.pt broken.py browser.zcml 
	configure.zcml 
Log Message:
Integrated new ZODB broken-object support with Zope 3, providing an
icon basic view for broken objects.  Also providing location support.

(A next step is to provide annotation support.)

Broken objects are objects who's class has gone away, typically
because modules or classes have been removed or moved.

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

<div metal:fill-slot="body">

<p>This object is broken because it's class can't be found.</p>

<p>This probably because the class' module, 
<strong tal:content="context/__class__/__module__">somemodule</strong>,
can't be found or because the name, <strong
tal:content="context/__class__/__name__">somemodule</strong>, is no longer
defined by the module.</p>
