Korzystając z ajaxa podmieniam dane dla list wyboru w zależności od wybranego kontrahenta. I pięknie to działa.

Problem w tym, ze jak chcę przeprowadzić walidację np czasu w polach 'plannedStartTime', 'plannedEndTime', to pobieranie danych do list przestaje działać. Gdy nic nie waliduję działa poprawnie.

Jak dopisać walidację do tego formularza by nie zakłócała ajaxowego podmieniania części tego formularza?
