Mike,
Thank for you explanation about the accessors for literals! Now I understand
why with Integer does not works.

Rather than String, try using Long for your accessors.
By default, accessors for literals must either be String or Long or Double.
#{1} is a new Long(1), not a new Integer(1).
Yes, a converter will work automatically, so if you were to provide
#{something that evaluates to an integer}, then everything would work
as you expect. But the problem is that you're not generating
Integers.
But, again, El returns Longs "#{1}", Strings "1", and Doubles "#{1.1}"
for literals, not Integers or any other type.
So if you had a facelets toInt() method, you could do:
"#{myFunction:toInteger(1)}"
Your other option is to do what Rene suggests and provide a method
that returns SelectItem<Label:String,Value:Integer> select items from
your java code

Hi Volker,
The problem also occurrs with itemValue="#{1}".
The solution was change the getter e setter to accept and return Strings:
public String getOpcao() {
return (opcao != null ? opcao.toString() : null);
}
public void setOpcao(String opcao) {
this.opcao = Integer.valueOf(opcao);
}
But, is not there a converter for this case?
Thank you,

Hi Rafael,
your itemValues are Strings, your bean expect Integer.
you can change the getter and setter to accept and return Strings
or try itemValue="#{1}", you may need to change from Integer to Number
than.

Hi,
I can't figure out why the following code results in "value is not a
valid
option":
<h:messages/>
<h:form>
<t:selectOneMenu value="#{bean.opcao}" id="opcao">
<f:selectItem itemLabel="Opção 1" itemValue="1"/>
<f:selectItem itemLabel="Opção 2" itemValue="2"/>
<f:selectItem itemLabel="Opção 3" itemValue="3"/>
</t:selectOneMenu>
<h:message for="opcao"/>
<h:commandButton value="OK"/>
</h:form>
public class Bean {
private Integer opcao;
public Integer getOpcao() {
return opcao;
}
public void setOpcao(Integer opcao) {
this.opcao = opcao;
}
}
Thanks,
Rafael Santini
