Bean Validation addon doesn't fire validation.

I’m trying to use Bean Vaidation addon.
I can’t use BeanValidationForm because my layout is not a Form.
I added the BeanValidatorValidator when I create the field.
All my fields have setImmediate(true).
When I insert a wrong value in the field it doesn’t fire any error message.
When I commit to dhe DB I get the error.
What did I forget ?
Where can I find an example without BeanValidationForm ?
