JSF 2 , noSelectionOption with Converter , Not working as it should

Question

I'm Migrating My project from seam 2 to JSF 2.x .

In seam 2 for enum's we have

<s:convertEnum />

which will call the converter when correct value is selected not the noSelectionOption value.

In JSF 2.x I have created My custom Converter like

@Named("enumConverter")
@ApplicationScoped
public class EnumConverter implements Converter {

public Object getAsObject(FacesContext context, UIComponent component, String key) 
        throws ConverterException {
if(!key.equalsIgnoreCase("-- Choose one --")){
    // DO LOGIC
}
return null;
}

public String getAsString(FacesContext context, UIComponent component, Object object) {
}

Now the problem is in my view I'm using the converter like

<h:selectOneMenu value="#{user.DocumentType}" required="true">
       <f:selectItem itemLabel="-- Choose one --" itemValue="#{null}" noSelectionOption="true"/>
        <f:selectItems value="${user.Constants(user.statuses)}"
            var="Val" itemLabel="#{user.Display(Val)}" 
        />
        <f:converter converterId="enumConverter"></f:converter> 
    </h:selectOneMenu>

Here if i select the NoSelectionOption then also my converter is getting called ,,, which should not happen and it should be called only if correct value is needed

in case of seam 2 converter only if correct value is selected then only converter will be called otherwise "value is required" is displayed.

Kindly please tell me ,what I'm missing here .... Appreciate and help ...

Thanks in advance

The above issue was due to a4j:commandlink which was having reRender attribute , i replaced it with render attribute and now message is getting displayed.

But now the issue is

*if required=true is not there and i select noSelectionOption then it will store blank value in DB. is it necessary to provide a validator in jsf 2 for noSelectionOption ????

Thanks
