I have this prototype (1.5) fragment that has historically worked, when 
I include rico.js the query is no longer sent to the server. The rico 
specific ajax stuff just makes no sense to me so I want to avoid using 
it, but I like the pretty decoration stuff.

 new Ajax.Updater("test","/ajax/ullist",{
                  encoding:'',
                  parameters:{text: $F("ftest")}});

Is the prototype ajax object shagged by rico.js or am I missing 
something??

I've got problems too after upgrading to prototype.js 1.5.0
None of my Ajax.requests are working anymore, they all silently die and 
nothing is send to the server.

Problems are gone if I comment out the rico.js (1.1.2) include.

Seems there is a bit of an incompatibility isse here.
I will look into it further but hopefully someone has come up with a fix 
:)

and yes a fix was already available add to this forum by Lucas Persona.

http://forum.openrico.org/topic/2228#new

not sure if I like to apply a fix to prototype.js instead of rico.js but 
at least there is a fix.

btw. this fix is also applicable for json.js 
(http://www.json.org/json.js)

Been there done that as they say, tried the fix, no success. Maybe I did 
something wrong, but it's not a difficult mod.

Is this supposed to be a definite fix or a maybe?

I did this fix, as the issue still isn't solved in Prototype, and it 
worked, but the Ajax.Updater still doesn't evaluate scripts in FF. IE6 
and Opera work fine.
Any Ideas?
