This is because the jQuery $ function is different from the prototype one, and RoR uses some particular function that is not available with jQuery.

For example, you can get an error like this submitting your remote_form_tag:

$(form).getElementsByTagName is not a function
http://localhost:3000/javascripts/prototype.js?1239274532
Line 3483

To solve this kind of problem, you have to use the jQuery no-conflict method, like explaned on the jQuery site. Simply add theese lines of code in your default layout between into a <script> tag:

jQuery.noConflict();
jQuery(document).ready(function($) {
})

Now, RoR can use prototype calling the default function $ and you can use jQuery using the jQuery function:

jQuery("#myId").hide("def");
