It works well but there are two problems:

  1. Labes are getting hidden when I submit for with errors, correct errors and resubmit the form. Is this case the fileds that were corrected lose their lable (the plugin puts display:none CSS property). It seams that this pugin mixes the original label with the error labes, and hides them when there is no error. How to fix this?
  2. Why for tesxtarea field when I correct the error, it immediately changes the class to success(which means it was corrected), while for input fileds I should resubmit the form so that the plugin start to validate?
