    Asdren Kuci Newbie

      Hi!


      I searched throw the forum and i found some posts about this topic but i still can't figer it out, where/what is the problem cause.


      The problem is:
      I have a form(generated from seam and then modified for my needs).
      When i want to search(filter) by between two dates it throuws these exceptions:
