You're not really helping yourself here.... Saying "it doesn't work" won't really get you very far. Have you put a debug breakpoint in? Have you seen a non null date?
> Maybe I should declare listaTiketa with @Persist You have a perfectly working example on tapestry stitch doing (almost) exactly what you need. Since the example doesn't use @Persist, I hope it's obvious that you won't need it either. Rather than bringing back all records from the database and filtering in the jvm. You should instead use a db query to filter the results. The stitch example is for simple demonstration purposes.
