Converter and SelectOneMenu problem

Question

<h:selectOneMenu id="id_noofbeds" value="#{internals.numberofbeds}" converter="javax.faces.Integer">
<f:selectItem itemValue="0" itemLabel="Studio" />
<f:selectItem itemValue="1" itemLabel="1" />
<f:selectItem itemValue="2" itemLabel="2" />
<f:selectItem itemValue="3" itemLabel="3" />
<f:selectItem itemValue="4" itemLabel="4" />
<f:selectItem itemValue="5" itemLabel="5" />
<f:selectItem itemValue="6" itemLabel="6" />
<f:selectItem itemValue="7" itemLabel="7" />
<f:selectItem itemValue="8" itemLabel="8+" />
</h:selectOneMenu>
I tried to run this code on my JSP page and have this in my backing bean:
public Integer getNumberofbeds() {
return numberofbeds;
public void setNumberofbeds(Integer numberofbeds) {
this.numberofbeds = numberofbeds;
But when I run this code it always comes back with a validation error. I think it's because SelectOneMenu sends things back as a tuple, but not exactly sure how to handle it. Any help would be appreciated!!

See the javadoc of UISelectOne.validateValue(). It says:
In addition to the standard validation behavior inherited from UIInput,
ensure that any specified value is equal to one of the available options.
If it is not, enqueue an error message and set the valid property to false.
You specify the options as String literals using f:selectItem.
So, the converted value which is type Integer is never equal to any of them.
You can't use literal value of f:selectItem. Instead you may code as<f:selectItem itemValue="#{bean.option1}" itemLabel="1"/>Using f:selectItems may be better:<f:selectItems value="#{bean.options}"/>
