Partials And the :index parameter

Greetings,

I have a Client model with a has_many relationship to an Email model. On my user form I am allowing the user to associate multiple email addresses to a client and assign one of them as the primary address. I have created a partial called _email that I am rendering as a collection from an @emails array.

My issues:

1) I cannot get the :index parameter to work with the text_field in the partial when rendering a collection of the _email partial. Relevant code.

<%= text_field :email, :address, :index => :email, :size => 25 -%>

The parameters list shows up as "email"=>[{"address"=>"address1@aol.com"}, {"address"=>"address2@aol.com"}]}

2) When a new client is first created, there are no email addresses associated with it, but i would like to render my partial with index 1 and then subsequent partials added afterwards via link_to_remote will continue that index numbering (2,3,4,etc). This may not work because of #1, but I thought I'd throw it out there all the same.

Help is greatly appreciated.

Thanks!
