Good moorning, guys!

I have two selectOneMenu components in my jsp. When I select some option of first component, the second component will be loaded in according of the first option.

Well, I did it. It works perfectly. The problem is when I save a new register, the system sends a validation message and don't save. It looks like the system thinks that I don't selected an option of second selectOneMenu. But I select!!!

The message does not exist in my project... Where does mesdage come from?

I need help. Thanks!
