java - Playframework ad-hoc form validation is executed but does not work as it supose -

i have login class validate method follow:

public static class login {          /** customer. */         @manytoone         @constraints.required         public customer customer;          /** password. */         public string password;           public string getpassword() {             return password;         }         public void setpassword(string password) {             this.password = password;         }         public customer getcustomer() {             return this.customer;         }         public void setcustomer(customer c) {             this.customer = c;         }          /**          * validate.          *          * @return string          */         @transactional         public string validate() {             return "global error";         }        } 

code form binding:

form<login> filledloginform = form(login.class); filledloginform.bindfromrequest(); 

when validate form follow:

if (filledloginform.hasglobalerrors()) {     return badrequest(views.html.login.render(filledloginform)); } else if (filledloginform.haserrors()) {     return badrequest(views.html.login.render(filledloginform)); } else {     return ok("ok"); } 

view:

<input type="hidden" id="customer_id" name="customer.id" value="@customer.id" />                                   @inputpassword(                                     loginform("password"),                                     '_label -> "hasło",                                     '_showconstraints -> false,                                     '_showerrors -> false                                 ) 

i ok page, there no error, in validate method i've declared it.

i use play 2.2.6

i suggest check explicitely in controller. like:

final string cid = form().bindfromrequest().get("customer.id"); if (filledloginform.hasglobalerrors()         || cid==null || cid.equals("")) {     // in case either there validation errors or provided customer.id not valid     return badrequest(yourtemplatehere.render(filledloginform)); } 

an alternative can try rewrite validate() method bit , check there (assuming there id field in customer class):

public string validate() {     return customer.id != null ? null : "oh no, customer id empty"; } 

p.s. having public fields , setters/getters @ same time bit confusing - switch either public fields or make them private , use getters , setters
