Sorry for the repost but I originally posted this as a response to  
another thread. I have a text field called ‘phrase’ but the  
parameter values always come up as nil and when I check the  
parameters dumped in the error message I do not get the normal hash  
you’d expect. Instead of something like

{“phrase”=\>“jim”}

I get:

{“jim”=\>"", “\_”=\>""}

Here is the code for the form:

Just a wild guess…I haven’t used the observe\_field method and don’t  
really  
know what it’s for but from the params you are getting it would seem the  
:phrase is not known. Try replacing :phrase with “phrase”.

Someone please correct me if I’m wrong.

thanks,  
andy

Nope,

I have had no luck. Changing that makes no difference. In fact if I  
take the raw post I get ‘jim&_=’ so no matter what value you type in  
there is an '&_=’ appended to it. Any ideas as to whats going on here?

&\_= is a workaround for a Safari bug, and gets added by Prototype  
(some versions of Safari are truncating POST data on Ajax calls).
