[jQuery] jQuery clone - problem with array inputs

[papercode]

Hi guys,

Inside myForm i have myTable.  myTable contains 3 text input fields:
name="ip[]"
name="mac[]"
name="netmask[]"

When a user clicks "add new" i clone myTable and append it to another
table inside myForm. Firebug sees no error in the generated html node,
yet when i press submit, the new fields don't get passed to PHP

$_POST['ip'] is a one-value array. So are mac and netmask.

Basicly, the new input elements seem to get ignored somehow.

I also checked whether the new fields are inside or outside the form
and they are definitely inside. Here's the clone code:

var js_new_ip = $('#ip_template').clone();

    js_new_ip.attr('id', '');
    js_new_ip.appendTo('#ip_holder');
    js_new_ip.contents().find("[name='ip[]']").val('');
    js_new_ip.contents().find("[name='mac[]']").val('');

Any thoughts?

Thanks
