Play 2.0 Java: Bind an array from request

Question

I... stuck o.O

I've params in foreign request:

param[62537]=abc;
param[20356]=cde;
param[92837]=fgh;

And I'm looking for any way for binding them ie. with DynamicForm.

I can get param with:

DynamicForm dynamicForm = form().bindFromRequest();
String firstParam = dynamicForm.field("param[62537]").value();

But of course I dont know the indexes as they are selected within the client-side form created by the independent app.

When I'm trying to use:

String[] firstParam = dynamicForm.field("param").value(); // it's NULL
String[] firstParam = dynamicForm.get("param"); // it's NULL

or even

String[] params = request().body().asFormUrlEncoded().get("param");
     // it's still NULL

Did I miss something really basic, or Play just can't do that?
