Rails spinoffs - Feb 2008 - Element.update not triggering scripts in Safari 3

I am having a very hard time debugging this. I have a form that I  
inject into the page using Ajax Updater, and submit using  
Ajax.Request. If the form is successful, I want to then insert the  
form content into an UL, but if it''s not correct, I need to update a  
different div (the one the form was initially injected into) with the  
form again, showing the errors.

So what I do is submit the form to its handler using Ajax.Request,  
and update the form DIV from within the onComplete function. If the  
form is bad, the handler will mark the bad fields and re-display it.  
But if it''s good, the handler sends back a little bit of HTML to say  
thanks, and a script block containing this line:

$(''reflist'').insert({top:''<li>stuff from
form</li>''});

I have this entirely working in Firefox 2, Firebug reports no errors  
at all.

In Safari 3, if I inspect the page, I can see that the correct  
JavaScript is coming back, but it''s apparently not firing.
I''ve tried
all sorts of things, even very basic alerts, but they''re not firing.

The code that should be firing is in a script tag, and the  
Element.update documentation clearly states that any such code will  
be executed when the element is updated. And in Firefox, this seems  
to be the case.

I am using 1.6.0.2.

Does this ring a bell for anyone?

Thanks in advance,

Walter

A bit more troubleshooting has unlocked part of the mystery. The code  
I am inserting is a full <li>, and I am adding it into an UL. So my  
fragment looks like this:

<li><p>A comment, just made by the person using the
form</p><p
class="author">—Person''s Name</p></li>

If I try to insert that using Safari, I get nothing -- no error --  
just nothing.

If I encode it in HTML entities, then it inserts, but of course  
displays as code -- not what I want.

If I encode it in HTML entities, then insert it with $ 
(''reflist'').insert({top:mycode.unescapeHTML()}), then it
ALMOST works
-- everything is fine except for the class="author" part, which  
Safari''s Web Inspector shows as being coded as
class=""author"" (and
of course does not honor).

Through it all, Firefox is a good soldier, and does what I want.

It seems as though the whole problem is with escaping characters  
while passing the string to insert, but I''m completely baffled how to  
get this to work. Should I try JSON encoding the parameter? Or maybe  
build up the inserted LI from DOM objects?

Thanks in advance,

Walter

Still more spelunking found another fix, related to the first. I had,  
in my code to be inserted, a Unicode em-dash. When I changed this to  
a decimal entity, everything worked again in Safari.

Very odd. I suppose that this is a Safari bug, since I can''t  
duplicate it on Firefox.
