Hi, I have tried to solve this issue for at couple of days with no luck. I have a form, where I use the validation plugin, and when I try to submit it, it submits empty vars. Now, if I remove the validation, everything works fine. Here is my implementation:

$(document).ready(function(){

 $("#myForm").validate({
  rules: {
    field1: {
      required: true,
      minlength: 5
    },
    field2: {
      required: true,
      minlength: 10
    }
  },
  messages: {
    field1: "this is required",
    field2: "this is required",
  },
  errorLabelContainer: $("#validate_msg"),
  invalidHandler: function(e, validator) {
    var errors = validator.numberOfInvalids();
    if (errors) {
        $("#validate_div").show();
    }
  },
  onkeyup: false,
  success: false,
  submitHandler: function(form) { doAjaxPost(form); }
 });
});

function doAjaxPost(form) {
  // do some stuff
  $(form).ajaxSubmit();
  return false;
}

As I wrote this does not work when I have my validation, BUT if I remove that, and just add an

onsubmit="doAjaxPost(this.form); return false";

to my HTML form, it works - any clue???

Now here is the funny thing, everything works as it should in Safari, but not in firefox 3.6.2 (Mac OS X)!
