Play framework Form object for multiple entities

Question

I am using Play 2.2.1 and got stuck in a situation. Basically I am working in a Jobportal application and I have a situation where the Jobseeker needs to fill his/her skills (with skill name, skill experience, etc). So for that I have created a separate entity Skill.

My problem is that the user have an option of adding multiple skills. So if the user enters only one skill I can simply do:

Form<Skill> sk=Form.form(Skill.class).bindRequest();

But if the user enters multiple skills how can I retrieve these multiple objects from form? I need something like:

Form<List<Skill>> sk=Form.form(Skill.class).bindRequest();

Means to retrieve list of entity object from form, the above line is just an explanation to what I want.

I have searched about this topic but didn't get any success. I also know I can simply use DynamicForm or request but it will give me individual columns, not the entity object.

Is this possible? If yes how can I achieve this?

Create a wrapper class for Skill class as follows:

public class Skills {

    private List<Skill> skills;

    // setters and getters

}

And bind it from request:

Form<Skills> skills = Form.form(Skills.class).bindRequest();

If you post a json, make it look as follows:

{
   "skills": [
      {
         // skill 1
      },
      {
         // skill 2
      }
   ]
}
