I used link-to-remote to update the Cart part in my Product page.
Since I wanted to allow submitting Amount, I tried moving to a form
and use 'update="carting"' instead. for some reason it doesn't work.
when I try it, the spinner displays but nothing change on the page
(the product seem to be in the cart but I need to reload the entire
page to see this)
my original link-to-remote:
<%= link_to_remote( "הוסף לעגלה",
{:update => "carting",
:loading => "Hobo.showSpinner('מעדכן עגלה');",
:complete => "Hobo.hideSpinner();",
:url => { :action => :add_to_cart, :id => this_parent }},
{:class => 'buy-button'}) %>
my updated form:
<form for="&this" action="products/add_to_cart" update="#"
method="POST">
<input name="id" value="&this_parent.id" type="hidden"/>
<input type="text" name="amount" title="כמות" value="1"
size="2"/>
<submit label="הוסף לעגלה"/>
</form>
my cart div:
<div id="carting" part="cart">
<partial name="cart" locals="&{:cart => @cart}"/>
</div>
the server log for my original link-to-remote:

there are only two differences, and I don't exactly know how to change
the form so it'll work closer to the link-to-remote (or change the
link-to-remote so it'll take the amount).
