Rails - Oct 2009 - output validations errors form causing type error?

Hi,

I was wondering if it is possible to output validation errors in a
nested form? I suppose this should be possible, but I am experiencing
an error message that I can''t track down.

The error I get is the following :
 TypeError in Store/orders#create
Showing app/views/store/orders/new.html.erb where line #45 raised:
can''t convert Array into String

This is ocurring in the following view code:
<% form_for :order, @order, :url => store_orders_url, :html => {:class
=> "myform"} do |order_form| %>
	<%= order_form.error_messages %>

I can''t understand why this would be ocurring, because I was able to
inspect the errors object for @order in the log, and it seems normal
to me, I don''t know why it cause errors in outputting errors to the
view for this object. Here is the output of the inspect method:

errors object #<ActiveRecord::Errors:0x105c343c0
@errors{"customer_billing_state"=>["must be present"],
"card_number"=>[["is
not a valid credit card number"]],
"customer_select_state"=>["^State/
Province must be a U.S. state selected from the drop down list for
customers in United States"], "card_verifiation"=>[["is
required"]]},
@base=#<Order id: nil, created_at: nil, updated_at: nil, customer_id:
nil, gst: #<BigDecimal:105d342c0,''0.0'',9(18)>, qst:
#<BigDecimal:
105d33ed8,''0.0'',9(18)>, shipping_ca:
#<BigDecimal:105d33ac8,''0.0'',9(18)
>, shipping_us:
#<BigDecimal:105bfb840,''0.7E1'',9(18)>, currency:
"USD", status: nil, comments: nil, customer_ip: "127.0.0.1",
payment_method: "Credit Card", downloaded: nil, express_token: nil,
express_payer_id: nil, card_type: "visa", card_expires_on:
"2009-10-01">>

If anyone has any idea where I can start looking to debug this error,
I would appreciated it very much.

Thanks,
Sean

Please ignore my post, I discovered what the problem was. I had been
manually adding errors to the order object from the validations of
another model (active merchant''s credit card class), and my mistake
was that I had added the errors directly, but the errors for each
attribute are an array of errors, so instead I just need to loop
through them and they add them to my order object using the errors.add
method. Just in case anyone else runs into a similar problem.
