[jQuery] Plugin Validate - Input text array validation

[JAC]

Hi,

I'm using validation plugin successfully in various forms, but I have
a little problem with a form that have an array of input text like
this:

...
<p>
   <label for="input_test_1">input_1</label>
   <input id="input_test_1" name="input_test[]"  />
</p>
<p>
   <label for="input__test_2">input_2</label>
   <input id="input__test_2" name="input_test[]"  />
</p>
...

I have defined validation rules like this:

$("#testForm").validate({
                rules: {
                        "input_test[]": "required"
                        }
                });

but only the first element of the array is evaluated.

Is there a simply way to test all the elements of the input text
array?

I'm using validation plug-in v1.2, and it's supposed to work with
arrays of element types or I'm wrong?

Thanks in advance.
