Programmatically generated components do not register with Bean Validation
--------------------------------------------------------------------------
Key: MYFACES-3299
URL: https://issues.apache.org/jira/browse/MYFACES-3299
Project: MyFaces Core
Issue Type: Bug
Reporter: Kennard Consulting
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?
