[Zope-Coders] Re: [ZC] 23/ 2 Comment "Small CMFDecor breadcrumbs fix"

[Gary Poster]

Acknowledged.  It is now reported on the CMF collector.  Sorry to bother you
(collectively).

I would close the listing on this Zope core collector if I could, but...I
can't.

Thanks

Gary

> CMFDecor breadcrumbs script is currently directly addressing portal url
and properties tools, instead of using the CMFCore utils.py getToolByName
function.  As I understand it, this direct call breaks (or at least hinders)
the ability to use arbitrary replacement portal tools in the CMF.

script must be external.  I modified the original script slightly to create
the following External Method (which I named CMFbreadcrumbs.py and placed in
my Extensions folder, but whatever):
