Obrigado pelas dicas. Vou tentar explicar melhor.
Tenho essa tela para incluir os preços dos produtos :
<ui:insert name="conteudo" >
<script type="text/javascript">
// Abre Popup Busca de Itens
function openPopup() {
features = "height=400,width=600,status=no,toolbar=no,menubar=no,location=no,scrollbars=yes";
window.open('../../../comercial/cadastros/tabelapreco/popupBuscaItem.faces', '', features);
}
// Carrega Itens
function carregarItem(id, nome) {
form = document.forms["fmEtiqLog"];
form[form.id + ":id"].value = id;
form[form.id + ":nome"].value = nome;
}
</script>
<h:form id="fmEditar">
<p:panel header="Incluir item na tabela de preço - #{tabelaPrecoFace.selectedBean.codigo}" style="background-color: #dddddd">
<table>
<tr>
<h:commandLink title="Salvar" action="#{itemTabelaPrecoFace.doSaveItemTabelaPreco(tabelaPrecoFace.idTabelaPreco)}" id="bt_salvar">
<p:graphicImage title="Salvar" value="#{pageContext.servletContext.contextPath}/resources/imagens/confirmar.png" width="20" height="20" alt="Salvar" />
</h:commandLink>
<h:commandLink immediate="true" action="#{itemTabelaPrecoFace.doListItemTabelaPreco}" title="Cancelar" id="bt_cancelar">

</h:commandLink>
</tr>
<tr>
<td>Item</td>

<p:inputText value="#{itemTabelaPrecoFace.selectedBean.item}" size="20" valueChangeListener="#{itemTabelaPrecoFace.itemNovo}" onblur="submit()" rendered="true" >
<f:converter converterId="itemConverter"/>
</p:inputText>

</h:commandLink>
<h:outputText value="#{itemTabelaPrecoFace.itemNovo.descricao}" style="color: #036fab"/>
</td>
</tr>
<tr>
<td>Preço unitário</td>
<td>
<p:inputText value="#{itemTabelaPrecoFace.selectedBean.preco}" styleClass="monetario" style="text-align: right">
<f:convertNumber type="currency" locale="pt_BR"/>
</p:inputText>
</td>
</tr>
<tr>
<td>% Desconto</td>
<td>
<p:inputText value="#{itemTabelaPrecoFace.selectedBean.desconto}" styleClass="decimal" style="text-align: right">
<f:convertNumber minFractionDigits="2" locale="pt_BR"/>
</p:inputText>
</td>
</tr>
</table>
<p:messages/>
</p:panel>
</h:form>
</ui:insert>Quando clico no botão pesquisar, abre o popup abaixo (até esta tudo funcionando legal) .

</html>O problema esta quando eu confirmo a seleção no popup, ele fecha, mas não atualiza o inputtext abaixo da tela principal (que chamou o popup).
<p:inputText value="#{itemTabelaPrecoFace.selectedBean.item}" size="20" valueChangeListener="#{itemTabelaPrecoFace.itemNovo}" onblur="submit()" rendered="true" >
<f:converter converterId="itemConverter"/>
</p:inputText>
