I have a weird issue.  I've been using the validation plugin for several months and have never had this problem.

 

field1 validation works great no problems.  regex is a custom validation rule that I wrote.  field2 doesn't show the error message unless I'm debugging the javascript. 

$("#myForm").validate({
 errorPlacement: function(error, element) {
  error.appendTo(element.closest('td').find('div.errorContainer'));
 },
 rules: {
  'field1': {
   regex: { param: urlRegex }
  },
  'field2': {
   required: { param: true }
  }
 }
});
