H:selectOnMenu nullo dentro do p:dialog

Olá pessoa, alguem já passou por esta situação, tenho alguns h:selectOneMenu dentro de um modal do prime, e quase todos vem nulos…

Minha pagina:



<comp:comboBox id="cidadeDestino"
	value="#{mBean.filtroRota.cidadeOrigem}"
	changeListener="false"selectItens="#{mBean.comboCidadesDestino}"
			label="#{msg.lblCidade}:" itemLabel="#{item.nome}"
		itemValue="#{item}" entity="true">
</comp:comboBox>

lembrando que o combo está dentro de um modal do prime…

nothing? nadica de nada?
