: value is not a valid option
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

Maybe :)
I've never tried it that way, but it sounds reasonable. However, I've
always wanted a more concrete type for my accessors than Number when
dealing with integer values.

Hi Mike,
didn't this mean changing the getter/setter from Integer to Number, as
suggested, should help?

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

Re: : value is not a valid option

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,

Rafael,
Rene is right -
in my case JSF bean has a property with type long,
and when I was creating the values for <f:selectItems/> tag I added manually
SelectItem(0, "All") to a collection,
must be SelectItem((long)0,"All");
not sure what to do in your case,
but I suggest to populate selectBox also by <f:selectItems/> tag

Hi Rafael,
the same happens in my project, I have slight difference - I'm populating

and when I select first "All" option jsf throws "Value is not valid",
otherwise it works fine. Really confusing case...
