One to one doubt

[nandolins]

i having some problems trying to persist an object with a one to one relation, it is working, but there must be a better way. Let me show you:
View:

<tr>
 <td>Codigo</td>
 <td><h:inputText value="#{assuntoProcesso.codigo}" required="true" /></td>
 </tr>
 <tr>
 <td>Descrição</td>
 <td><h:inputText value="#{assuntoProcesso.descricao}" required="true" /></td>
 </tr>
 <tr>
 <td>Codigo Natureza</td>
 <td><h:inputText value="#{naturezaProcesso.codigo}" required="true" /></td>
 </tr>
 <tr>
 <td>Descrição Natureza</td>
 <td><h:inputText value="#{naturezaProcesso.descricao}" required="true" /></td>
 </tr>

Action:

@In
 @Out
 @Valid
 private AssuntoProcesso assuntoProcesso = new AssuntoProcesso();

 @In
 @Out
 @Valid
 private NaturezaProcesso naturezaProcesso;

And setting the variable naturezaProcesso to assuntoProcesso then.
but this looks kind of stupid, declaring the two variables, it would be much more simple to use a view like this:

<tr>
 <td>Codigo</td>
 <td><h:inputText value="#{assuntoProcesso.codigo}" required="true" /></td>
 </tr>
 <tr>
 <td>Descrição</td>
 <td><h:inputText value="#{assuntoProcesso.descricao}" required="true" /></td>
 </tr>
 <tr>
 <td>Codigo Natureza</td>
 <td><h:inputText value="#{assuntoProcesso.naturezaProcesso.codigo}" required="true" /></td>
 </tr>
 <tr>
 <td>Descrição Natureza</td>
 <td><h:inputText value="#{assuntoProcesso.naturezaProcesso.descricao}" required="true" /></td>
 </tr>

But i getting errors with this one, anybody can help me?

[knaas]

Please post a description/log of the errors that are occurring.

[nandolins]

it doesnt give me a specific error, just gives me the message "conversion error" in the view.

[knaas]

What about the server's log file? If a conversion error is occuring, I would expect something like a NullPointerException or a ClassCastException.

It sounds more like a JSF issue than a Seam issue.

[nandolins]

nothing at the log oO
what kind of JSF issue?

[nandolins]

another thing that looks kind of strange is that using the same thing to read from the database works, the problem happens only when i-m trying to write to the database.

I see "Conversion Error" too in my web page, generated by the <h:messages/> element.

I don't see any exceptions at all, no NullPointer or ClassCastExceptions.
