Seam - Popular selectOneMenu com objetos

Front-end
#1

Colegas,
A tag <s:convertEntity/> me retorna um nullPointerExceprion.
Existe algo que tenha que mudar no components.xml para que a mesma funcione?
Onde estou errando?

Muito obrigado,

Marques

<h:selectOneMenu value="#{person.occupation}">
  <s:selectItems var="_item" value="#{occupationList}" noSelectionLabel="Select..." label="#{_item.name}"/>
  <s:convertEntity/>
</h:selectOneMenu>

Meu components.xml:

[code]

<?xml version="1.0" encoding="UTF-8"?>

<core:manager conversation-timeout=“120000”
concurrent-request-timeout=“500”
conversation-id-parameter=“cid”/>

<transaction:entity-transaction entity-manager="#{em}"/>
<persistence:entity-manager-factory name=“lojaPU”/>
<persistence:managed-persistence-context
name=“em”
auto-create=“true”
entity-manager-factory="#{lojaPU}"/>

<security:identity authenticate-method="#{authenticator.authenticate}"/>
[/code]

Ninguém?
