How to force validation of Seam components bound to the UI t

[grettke_spdr]

Hi folks,

Due to our architecture we are binding Seam components to the UI that happen not to be JPA entities.

Still, we would like to define the component validations using the Hibernate Validator annotations.

Out of the box, when we use the validateAll tag, the validations don't get performed. My take on this is that since the component bound to the UI is not a JPA entity, the validation doesn't get run.

As a work around, I added @Valid to the injection of this component into an action and @IfInvalid(outcome=Outcome.REDISPLAY) on the action method. This seems to force the validation, but now, the validation doesn't seem to get displayed nicely on the web page itself (for example if I add required=true to that component the decorator works correctly).

* classes do *not* need to be entities to be validated by s:validateAll
* @IfInvalid has been deprecated for a long time and was removed from Seam2

So you should figure out why s:validateAll was not working for you.

We are using the s:decorate, and in particular with the default edit.xhtml as the template. When we specify the control (in this case a h:selectManyCheckbox) as required, the decoration works correctly. That template uses validateAll internally. It *looks* like validateAll is working correctly.

When I remove the required and just depend on the validator annotations to run, they don't.

Any pointers on this one?

I will look into it further.

Well, thats a FAQ. JSF validators cannot validate null values. So @NotNull is ignored. You need to use required=true for that. Then you can use Hibernate Validator annotations for validating the entered value.

Right, I remember reading about that bit, JSF won't validate anything unless you specify required=true.

Thanks Gavin.
