[jQuery] Radio button validation

[jQuery] Radio button validation


I've got a bunch of radio buttons, all with the name "type" and all
with different id's (type1, type2 etc.), and for some reason the
validate plugin doesn't protest when I don't select a radio button,
and I don't get any javascript errors either. Here's the code:
$("#addForm").validate({
    focusInvalid: false,
    event: "blur",
    rules: {
        type: { required:true }
    },
    messages: {
        type: "Please choose type"
    }
});
-------------------------------------
And here's the html
<label for="type1">
<input type="radio" name="type" id="type1" value="1" />Type 1
</label>
<label for="type2">
<input type="radio" name="type" id="type2" value="2" />Type 2
</label>
-------------------------------------
Anyone got a clue?
Thanks!
