Manual entity validation with Seam-like feedback

[wilczarz.wilczarz.gmail.com]

Is it possible to perform manual entity validation and provide feedback exactly like the one provided by Seam?

The following pseudocode stops the pageflow but displays plain jsf message in <h:messages>:

if( !isValid( entity ) {
  InvalidValue iv = new InvalidValue( "wrong value", SomeEntity.class, "someProperty", null, entity );
  facesMessages.add( iv );
  return "/theSamePage.xhtml";
}

I'd like to have <s:message> filled and the input coloured with error css class. I also tried addToControl method but efeect was the same.

facesMessages.addToControl(
        "invalidControlId", 
        new FacesMessage(FacesMessage.SEVERITY_ERROR,"it is bad","oh so bad")
);

Note the

SEVERITY_ERROR

Still the same - messages render in <h:messages> and the inputs are not hilighted. I'm inside a long-running conversation, does it matter?

Ok, this code does the job:

import javax.faces.context.FacesContext;
FacesContext.getCurrentInstance().addMessage( 
        "invalidControlId", 
        new FacesMessage(FacesMessage.SEVERITY_ERROR,"it is bad","oh so bad");
);

This is weird though, not to be able to use the injected component.

I read this and tried:

this.facesMessages.addToControl("formEditPatient:nameFirst", new FacesMessage(FacesMessage.SEVERITY_ERROR, msgRequiredField, msg));

Where the client-id is made up the explicit h:form and h:inputText component names.

It didn't work. Looking at the page source, I found:

div id="formEditPatient:nameLast"
...
input id="formEditPatient:nameLast:nameLast" type="text" name="formEditPatient:nameLast:nameLast"
...

Which is definitely NOT what I expected. I put the nameLast:nameLast in the program code and the field is still not highlighted and the summary isn't showing up.

I would never name any control like this. Is there a way to control how Seam generates object names?
