[jQuery] $.ajax behaviour change in 1.2 ?

[jQuery] $.ajax behaviour change in 1.2 ?


hello.
i've noticed a modification in $.ajax() function.
$.ajax({
    type: "POST",
    url: 'mypage.php?smth=2',
    data: "action=action",
    dataType: 'json',
    success: function(){
    }
})
previous to 1.2 this function was sending "action" using POST to
'mypage.php?smth=2'
in 1.2 it is sending "action" and "smth" to "mypage.php" .
do you know of any way to make it work as before?
thank you
