p:commandButton inside p:dialog does not work - jsf

Question

I have this problem and I search here and some pages on Google and none of the answers worked for me.
I have the following dialog:
<!-- Dialog Fechar Pedido -->
<p:dialog header="Fechar Pedido" widgetVar="clsPedido" id="clsPedido" minWidth="550">
<h:form prependId="true" id="frmClsPedido">
<p:panel id="pnlDialogClsPedido" header="Informe a forma de pagamento">
<h:panelGrid id="grdClsPedido" columns="2" cellpadding="5">
<p:outputLabel value="Valor Total:." />
<p:outputLabel value="R$ #{pedidoMB.totalPedido}" size="5" style="color: red;">
<f:convertNumber currencySymbol="R$" integerOnly="true" pattern="#0.00" locale="pt_BR" minFractionDigits="1" minIntegerDigits="1" />
</p:outputLabel>
<p:outputLabel value="Valor Recebido:." />
<pe:inputNumber id="vlrRecebido" value="#{pedidoMB.vlrRecebido}" minValue="0" required="true" onblur="returnValue(this.value)" requiredMessage="Informe o valor recebido!" decimalPlaces="2" decimalSeparator="," thousandSeparator="." />
<p:outputLabel value="Pagamento em:." />
<p:selectOneRadio id="frmPagamento" value="#{pedidoMB.frmPagamento}" onchange="daTroco(this.value);" required="true" requiredMessage="Informe a forma de pagamento!">
<f:selectItem itemLabel="Dinheiro" itemValue="DIN" />
<f:selectItem itemLabel="Débito" itemValue="DEB" />
<f:selectItem itemLabel="Crédito" itemValue="CRED" />
<f:selectItem itemLabel="Vale Refeição" itemValue="REF" />
</p:selectOneRadio>
<p:outputLabel value="Valor Troco:." />
<p:inputText value="#{pedidoMB.vlrTroco}" size="5" style="color: blue;" id="vlrTroco" widgetVar="vlrTroco" readonly="true">
<f:convertNumber currencySymbol="R$" integerOnly="true" pattern="#0.00" locale="pt_BR" minFractionDigits="1" minIntegerDigits="1" />
</p:inputText>
</h:panelGrid>
<h:messages></h:messages>
<div align="right">
<p:commandButton icon="ui-icon-disk" actionListener="#{pedidoMB.doFecharPedido}" />
</div>
</p:panel>
</h:form>
</p:dialog>
And I have the following method at my mbean:
public void doFecharPedido(ActionEvent event) {
if (getId() != null) {
Pedido p = getService().findById(getId());
getService().fecharPedido(getVlrRecebido(), getVlrTroco(), p);
}
}
I already tried removing the mbean ActionEvent but nothing seems to work.

Answer 1

Why not simply write
<p:commandButton icon="ui-icon-disk" action="#{pedidoMB.doFecharPedido}" />
and
public void doFecharPedido() {
if(getId() != null) {
Pedido p = getService().findById(getId());
getService().fecharPedido(getVlrRecebido(), getVlrTroco(), p);
}
}
?

Answer 2

The problem was a validation error. For some reason the inputNumber from PF extension does not accept a paste value or some other form of automatic fill of the field.
