I'm trying to implement the following functionality. I have a
"has_many" association, let's say User and Phones.
I would like to create/edit Phone numbers while editing/creating a
user. So I have a subform in phones_controller, and my user create/
edit form looks good with phones included in it.
Only one Phone number is primary, so I'm adding a checkbox "Primary"
to the Phone subform (dont' believe it matters, but "is_primary" a
virtual field). If there are multiple phones, any time any "Primary"
box is checked, I'd like to uncheck all the others.
I thought about using subform override to add an onclick callback to
the checkbox, so I can change the values of the other checkboxes. I'm
trying to follow this doc:
http://wiki.github.com/activescaffold/active_scaffold/subform-form-overrides
So I have app/views/users/_is_primary_form_column.rhtml with this:
<dt><label>Another label</label></dt>
<dd>
<%= check_box("user", "is_primary",
{:onclick => remote_function(:url => {:action =>
"on_primary_change"},
:with => "'is_primary='+value")}, "aha", "nien")
%>
</dd>
and I have on_primary_change method in my users_controller.
"Another label" never appears, so it looks like the override is not
used at all. However, the callback attempts to kick in (although NOT
every time I click on the checkbox), but fails with this:

Thanks for your help! Also if you know any other way to implement this
functionality, could you please let me know.
