[kupu-dev] kupu filtering "class" attribute from links

[Rick Moore]

One of our web sites (Birds of North America - 
http://bna.birds.cornell.edu) has over 11,000 articles about birds. The 
original content was downloaded from an old Fatwire database and 
inserted directly into the text field of the documents. Each of these 
articles may contain dozens of bibiliographic references that are 
supposed to shown in small popup windows when selected. Because of all 
the religion against the onClick. attribute, we do this using the class 
attribute on the <a> tag.

This worked fine until recently, then blew up when we started to update 
the articles for some of the birds. Once the content is changed in kupu, 
all the class attributes are stripped from the <a> tags and the popup 
trigger no longer functions.

I posted this on the plone-users web site and ttried looking at 
kupubasetools,js and kupucontentfilters.js as suggested. I am not a 
javascript programmer, so I was somewhat bewildered by what I found. It 
seems that kupubasetools.js specifically allows the "class" attribute 
for practically everything. But then the code in LinkTool seems to want 
to strip it out if it wasn't set by the one of the link buttons in the 
kupu UI.

I need somewhat explicit help in figuring this out. Is there anyone who 
can tell me where the class attribute gets stripped out of links and how 
I can fix it.  I have no aversion to upgrading to a later rev of kupu if 
that will help. And I'd be willing to add a special link button if 
that's what it takes, just don't know how.

We are using :
kupu 1.3.9
Plone 2.5.4
Zope 2.9.7
Python 2.4.4
Red Hat Enterprise Linux
