Rails - Oct 2006 - link_to_remode :id

Hi,

After using rails for a while, I''ve decided to
''sex-up'' my apps using
the built in AJAX support.

I seem to have struck a problem which is probably my own oversight.

When I make a call to link_to_remote, I want to send an :id to the
action. When this is handled by a stadard link_to call, it''s fine.
Using link_to_remote causes the error: ''You have a nil object when you
didn''t expect it!''.

In summary:

<%= link_to ''Capabilities'', :action =>
''capabilities'', :id => @mything
%>

...is OK, but...

<%= link_to_remote("Capabilities",
:update => ''mydiv'',
:url => { :action => ''capabilities'', :id => @mything
}) %>

...does not.

Maybe i''m just too old and my head is wired for Web 1.0 :)

Thanks for any help anyone can give.

Where is the error being raised from?
