Leonardo Uribe commented on MYFACES-3299:
-----------------------------------------
It is expected that no bean validation be bound to programatically added
components. It is responsibility (at least theorically) of the developer to
check the conditions and add bean validation in this case. I don't see how to
solve it in other way.
> Programmatically generated components do not register with Bean Validation

> I am having problems using MyFaces with Bean Validation.
> I am not clear what the JSF spec means, but it says "Consider a simple web
> application that has one page, written in Facelets for JSF 2, that has a
> several text fields inside of a form. This application is running in a JSF
> runtime in an environment that does require JSR 303 Bean Validation, and
> therefore this feature is available. Assume that every text field is bound to
> a managed bean property that has at least one Bean Validation constraint
> annotation attached to it. During the render response phase that always
> precedes a postback, due to the specification requirements in Section 3.5.3
> "Validation Registration", every UIInput in this application has an instance
> of Validator with id javax.faces.Bean attached to it".
> George Gastaldi and I have created a sample application (attached) that
> demonstrates several ways of creating a simple input text bound to Bean
> Validation. This must be deployed to a Java EE 6 container (we tested against
> JBoss AS 6). You will note the first two pages (Normal Facelets form, Binding
> Component) work fine. When you click 'Click Me' to POSTback, Bean Validation
> is invoked and a validation error is displayed.
> The second two pages (Dynamic Component, Dynamic Component (with Metawidget))
> do not work as expected. They both use PreRenderViewEvent to create the
> inputText programmatically. The spec is unclear whether we're meant to
> explicitly add a javax.faces.Bean validator in this case? The way I read
> section 3.5.3, I don't think we do, but it doesn't work without it?
