How to get full form validation error message without form helper in Play Framework 2?

Question

As HTML forms can come in many different shapes, I'd like to understand how to create individually designed forms without creating input helpers for each case. All examples I could find deal with form helpers.

In my controller I've got something like this:

formWithErrors => BadRequest(views.html.formsamples.getform1(formWithErrors))

My view:

<div class="form-group@{if(form.error("age")) " has-error"}">
    <label for="exampleInputAge1" class="control-label">Age</label>
    <input type="text" class="form-control" name="age" id="exampleInputAge1" placeholder="Enter age">
    @if(form.error("age")) {
        <span class="help-block">(1) @form.error("age")</span>
        <span class="help-block">(2) @form.error("age").get.message</span>
        <span class="help-block">(3) @Messages(form.error("age").get.message, form.error("age").get.args)</span>
    }
</div>
@helper.inputText(form("age"))

The error output looks like this:

(1) FormError(age,error.max,WrappedArray(100))
(2) error.max
(3) Must be less or equal to WrappedArray(100)

Number (3) is as close as I can get, but it's still not the correct error message, because as I understand @Messages takes separate arguments required for the translation, whereas form.error("age").get.args provides the arguments as a WrappedArray.

When I use Play Framework's default input helper, the (first) error message is: Must be less or equal to 100

How can I get to this message including all arguments required to translate a full error message?

(The full view file can be found on GitHub.)

To use an array (or similar collection) you can use the following:

def method(args:String *):Unit

method("one", "two")

method(Seq("one", "two"): _*)

This is the line in the source code of the play framework: Helpers.scala#27
