Validation of non-ui fields

[nickarls]

Hello,

What is the cleanest way of validating domain objects (e.g. some fields that don't have ui components bound). Should I use a ClassValidator and then move the errors to the facesmessages myself or is there a cleaner way?

That is the approach we have taken. It works.....fine is the appropriate word.

Another idea would be to bind the values to a h:inputHidden. Using Hibernate Validator's @AssertTrue and @AssertFalse you could do some incredibly complicated validations without needing to RYO validators.

This is an interesting requirement. You can use the validators component to help you here.

Pardon me but what do you mean by "the validators component"?
