Form (). bindFromRequest () with array values

Question

I have <select name="items" multiple> in the interface and I use form (). bindFromRequest () to the backend, and then using DynamicForm.

But here is hic:

 DynamicForm form = form().bindFromRequest(); form.field("items").value(); // Only return one value ! 

How can I get all the value presented? without having to go through request().body().asFormUrlEncoded().get("items") , if possible.

Thank you for your help!

Answer 1

Binding array values ​​require the correct value to be specified in the query. The parameter name must end with "[]" to bind as an array (list) value.

In your HTML you should have:

 <select name="items[]" multiple> 

In the form class add it as:

 public class ExampleForm { public List<Integer> items; } 

I know that this does not solve the DynamicForm problem, but it is a much more elegant solution.
