Try something along this line
private SelectItem item;
public selectItem getItem() {
return new SelectItem(someValue, someLabel);
// someValue is your Integer and someLabel the String you want to display
// more information can be found in the Javadocs on how to use SelectItem
}
public void setItem{...}
You can also try the tag f:selectItems which expects, for example a List
containing SelectItem objects
private List<SelectItem> items;
public List<SelectItem> getItems() {
items = new ArrayList<SelectItem>();
for (Something something: AllSomeThings) {
items.add(something.getValue, something.getLabel);
}
return items;
}
with a corresponding setter if you need one.
Processing whole collections is not really a good way to proceed, but if the
collection is of a reasonable size it should give a good performance.
But is the size increases considerably this not a good option, performance wise
that is.

Subject: Re: : value is not a valid option
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 Santini

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.
