Scala Playback variable transfer view does not work

Question

This code works fine:

In the controller:

Ok(views.html.payment(message,test,x_card_num,x_exp_date,exp_year,exp_month,x_card_code,x_first_name,x_last_name,x_address,x_city,x_state,x_zip,save_account,product_array,x_amount,products_json,auth_net_customer_profile_id,auth_net_payment_profile_id,customer_id)) 

In view:

 @(message: String, test: String, x_card_num: String, x_exp_date: String,exp_year: String, exp_month: String, x_card_code: String, x_first_name: String, x_last_name: String, x_address: String, x_city: String, x_state: String, x_zip: String, save_account: String, product_array: Map[String,Map[String,Any]], x_amount: String, products_json: String, auth_net_customer_profile_id: String,auth_net_payment_profile_id: String,customer_id: String) 

But when I try to add another variable to the controller and see like this:

 Ok(views.html.payment(message,test,x_card_num,x_exp_date,exp_year,exp_month,x_card_code,x_first_name,x_last_name,x_address,x_city,x_state,x_zip,save_account,product_array,x_amount,products_json,auth_net_customer_profile_id,auth_net_payment_profile_id,customer_id,saved_payments_xml)) @(message: String, test: String, x_card_num: String, x_exp_date: String,exp_year: String, exp_month: String, x_card_code: String, x_first_name: String, x_last_name: String, x_address: String, x_city: String, x_state: String, x_zip: String, save_account: String, product_array: Map[String,Map[String,Any]], x_amount: String, products_json: String, auth_net_customer_profile_id: String,auth_net_payment_profile_id: String,customer_id: String, saved_payments_xml: String) 

This gives me this error:

 missing parameter type 

What am I doing wrong?

Answer 1

There is a limit on the number of parameters that you can pass to template . You exceeded it when you add another parameter.

This is an undocumented and rather arbitrary limit, which is the result of how code generation from the template works. This may be a mistake, but not one that I would fix, since no one needs this many parameters, and with this many make the code much less readable.

Your best solution here is refactoring, for example, by creating some case classes to represent the map and address in your model and pass them instead.
