Hello there,

I have a live search that gimme a list of products.  
In that list, I have a link for each product. That link render the  
product page.

The problem is: After the product page renders, the observe\_form calls  
one last time, and generates an error, because of an invalid div.

Does anyone now why?

Tks

David S.

Neither did I. I have a similar problem with observe\_form, using it  
for validations.

It fires a PUT for each field change I make, and a POST (to my  
validation controller method) after the changes are submitted to the  
server.

Same here, I notice the same behaviour, when changing a field a PUT is  
sent, why?
