Converter "javax.faces.Long" never called for af:selectOneChoice

[Martin Koci]

I have simple form:
<h:form>
<af:selectOneChoice id="idSubComitee"
value="#{s012modelId.publicationWGBlockModel.insertDto.idSubComitee}">
        <f:converter converterId="javax.faces.Long"/>
        <f:selectItems value="#{comiteeciselnik.selectItems}" />
</af:selectOneChoice>

<af:commandButton text="OK"/>
</h:form>

But instance of org.apache.myfaces.adfinternal.convert.LongConverter or
javax.faces.convert.LongConverter is never called after clicking OK
button.  h:selectOneMenu works fine in same case.

Is that expected behavior?

Thanks, 

Martin
