Play Framework 2.2.1 - Compilation error: "the render method in the class index cannot be applied to the specified types";

I am new to the Play Framework and trying to build a Todo list from this guide.

When I try to start the application, I get an error message:

Compilation Error
error: method render in class index cannot be applied to given types;

My code (relevant parts):

MainController.java :

final static Form<Task> taskForm = Form.form(Task.class);

public static Result tasks() {
    return ok(
            views.html.index.render(Task.all(), taskForm)
    );
}

index.sacala.html

@(tasks: List[Models.Task], taskForm: Form[Models.Task])

I looked around, the nearest thread that I found was this one, but I could not solve the problem using it (perhaps due to a lack of understanding of the environment / structure ...).


One last thing worth mentioning: If I change index.sacala.html to no parameters (and change "MainController" accordingly, everything will work fine.

.

EDIT:
Task.all():

public static List<Task> all() {
    return new ArrayList<Task>();
}
