Rails - Aug 2006 - problem inserting parameters in link_to_remote

I want a page that lets users add members to a group
from a longer list, or remove members from that group.
 I can use Ajax to transfer a name from the long list
to the group, or drop an existing name from the group.

But.

If I add a person to the group, and try to remove
without refresh, it doesn''t work.  My link is formed
by <%= link_to_remote ''add'', :url => { :action =>
"remove_member", :id => person.id, :group_id =>
group.id"} %>  For a member who''s in the group when I
reach the page, that generates a call to
/controller/remove_member/person.id?group_id=group.id
as it should.  But if I add a member ''foo'' to the
group and then try to remove the same person, the call
is controller/remove_member/foo.id.

I''ve been able to hack around it by setting :id =>
"#{person.id}.{group.id}" in the link_to_remote, but
there''s got to be a better way.

Thanks, but that doesn''t address the problem that the
parameter isn''t being passed to the action in the
first place.  Does it?  I mean, I can add a member to
a group just fine; the problem is that after I''ve
added a member, and used a remote call to update the
members list, it''s not possible to do a remote call to
remove that same member because for some reason the
inserted link_to_remote for the new member just drops
the group_id parameter.  How does REST fix that?

And speaking of dropping parameters, does anyone know
how to respond to a thread on this list from a
web-based mail account?

Post you controller and partial code and maybe someone on the list can
better help.
You should be able to simply reply to this email from your web-based
mail account.
