Trouble Accessing Ruby Params on RhoMobile

Question

I'm new to Ruby so please excuse my ignorance. I really didn't know how to word this question so this may also be part of the reason I haven't found an answer online.

I'm working with Rho Elements, and I'm trying to pass something from one page to another. I've made some good headway but run into something that I do not understand. I can pass through an ID like so

<input type="hidden" name="id" value="<%= @orderdetails.object %>"/>

I then grab the ID(only doing this right now to make sure I do get the ID)

@id = @params['id']

then redirect to another page

redirect url_for(:action => :newpage, :id => @id).

This is where my problems start. When I debug the application I get past the redirect and enter :newpage

def newpage
    @orderdetails = OrderDetails.find(@params['id'])
    if @orderdetails
      render :action => :newpage, :back => url_for(:action => :index)
    else
      redirect :action => :index
    end
end

Once here I check

@params['id] 

and this is what is displayed.

@params {"id"=>"{131113212443313.17}"}  
"id"    ""  

@params {"id"=>"{131113212443313.17}"} is shown by eclipse and when I break into the variable "id" "" is shown.

Why can I see the ID that I want to use to grab the orderdetails that was just created but also have the actual variable be empty?

**EDIT: This is the information I'm trying to pass.

@params {"id"=>"131113212443313.17", "next"=>"asleftnext", "orderdetails"=>
{"AsFoundMeterRead"=>"", "AsFoundImage"=>""}}   
"id"    "131113212443313.17"    
"next"  "asleftnext"    
"orderdetails"  {"AsFoundMeterRead"=>"","AsFoundImage"=>""}

Use params in the controller, not @params. Also the canonical form of accessing keys is params[:id].
