Hi Fabrizio,
I did some fixes in the AJAX block after 2.1.8 release, can you try to
from the lastest SVN code and report back if the issue is already fixed?
Best Regards,
Antonio Gallardo.

Hello,
I've digged a bit in the source myself ...and found out two things:
1. The "optNxxxxx is not defined" Javascript error is apparently caused by
the optNxxxxx variable being initialised in a local scope instead of the
document's global scope.
( For non-IE browsers, this can be fixed by replacing the line containing
"eval(scripts[i]);" in cocoon-ajax.js with "setTimeout(scripts[i], 10);" )
2. But even if the optNxxxxx variable is initialised all right, you will
stumble upon other stuff not being initialised correctly:
The 'double-listbox' widget relies on an object (OptionTransfer) that is
normally initialised by a document onLoad() handler.
That is fine for full page reloads, but with partial updates via Ajax, the
onLoad() handler for a freshly added 'double-listbox' widget is never
going to be executed!
I've looked at the bug report you mention below (COCOON-1718), and have
merged the changes to my 'cocoon-ajax.js' file, but it doesn't appear to
fix the global var-, nor the onLoad- issues with the 'double-listbox'
widget.
I'm currently working on a fix, tbc.
Thanks for your reply,
Fabrizio
Looking at the source, I believe this is due to the fact that
<script></script> contents received via AJAX requests are executed
before they are added to the main page's DOM, not after. The styling
for double-listbox includes a snippet of script that calls a global
function to hook up event listeners etc., and this fails because at the
time it is run the elements aren't yet part of the document.
There is a bug report in Jira [1] about scripts being run too soon;
someone attached a preliminary approach for a fix but it seems there are
still issues with it. Not sure if that helps or not.
