Rails - Apr 2008 - Problem with UUID generated in partial not being unique

Folks,

I''m using the "uuidtools" package to generate (hopefully)
unique values for
IDs within a partial (for products being added to an order form, where 
nothing is saved to the DB until the end).

Unfortunately when I add a new product line (using RJS page.insert.html 
rendering a partial) the new lines added all have the same UUID.

Here''s the code from the (top of the) partial -

<tr class="order_product" id ="<%= if
order_product.new_record?
         UUID.random_create.to_s
      else
         order_product.id.to_s
      end
    %>">

If we have a new product added then we generate a UUID.  If it is in edit 
mode, and we have an existing database record we using the ID of the record 
as the ID.

When I generate the page initially it puts one product line in place.   It has 
a UUID value.   When I click my link to add a new line, it has a different 
UUID : but adding any further rows still use this second value.

Is there some sort of caching going on ?   Or is there some other reason ?

TIA

Phil

How exactly are you doing this? if it''s all happening client-side then
this is to be expected: the partial is only rendered once (how could  
it be rendered more than once if there is no roundtrip to the server.
