multiple values in inputText? (JSF)

Question

Is there a way to associate the return value of an inputText with more than one attrribute?

Like this (it's a sample, value1 and value2 tag attributes does not exist in the syntax):

<h:inputText id="matricula" 
             value1="#{alunoController.aluno.matricula}" 
             value2="#{alunoHasCursoController.alunoHasCurso.matricula}">
</h:inputText>

Thanks in advance!

`value` is a predefined attribute in the framework. You can't define your own attributes as `value1,value2...` and did you try to keep this format in your page and check? — SRy, Mar 07 '13 at 23:57
This is a code smell. I don't believe the capability exists and for good reason. It's sloppy design. — kolossus, Mar 08 '13 at 02:11

Maybe just pass inputText value directly to bean method (described here) and in this method you can associate it to multiple variables/fields.

I will explain deeply my problem> I have two models: Student and Student_has_Course Both models have the attribute registration. I need to make both models have this attribute registration set with the same value, received by the inputText. Or there is a way of inside one model, access another to catch the value without reinstantiate it? – Johann Gomes Mar 08 '13 at 00:40
@JohannGomes, please explain the concrete problem in the actual question – kolossus Mar 08 '13 at 02:08

Use an f:valueChangeListener to cause the changes to be sent to the second bean.

<h:inputText
    value1="#{alunoController.aluno.matricula}" 
    value2="#{alunoHasCursoController.alunoHasCurso.matricula}">

Why do you need copies? This is bad design. Java is object oriented and allows you to reference a single object instance by multiple references.

You just need to ensure that #{alunoHasCursoController.alunoHasCurso} references exactly the very same #{alunoController.aluno} instance.

E.g.

public class AlunoHasCursoController {

    @ManagedProperty("#{alunoController.aluno}")
    private Aluno alunoHasCurso;

    // ...
}

So that you can get away with

<h:inputText
    value="#{alunoController.aluno.matricula}">

Or the other way round, depending on the context and functional requirement.
