validation and rich: popupPanel don't work

My intention is to display a message to the user in a rich: popupPanel after insert a record in BD.

With the code below I get to do what I want, but with a problem. Only works when I type all page fields correctly. If one of the fields does not pass in validation, the validation message is displayed in the h:messages, and the page does not change, even if I change the contents of the field and click the button again.

What could be wrong?

• page

  <h:outputLabel value="Nome:" for="nome1" />
  <h:inputText id="nome1" maxlength="50" required="true" requiredMessage="Informe um nome" immediate="true"/>
  
  <h:outputLabel value="Logradouro:" for="logradouro" />
  <h:inputText id="logradouro" maxlength="50" required="true" requiredMessage="Informe o logradouro" immediate="true"/>
  
  <h:outputLabel value="Bairro:" for="bairro" />
  <h:inputText id="bairro" maxlength="45" required="true" requiredMessage="Informe o bairro" immediate="true" />
  
  <h:outputLabel value="CEP:" for="cep" />
  <h:inputText id="cep" maxlength="8" required="true" requiredMessage="Informe o CEP" immediate="true">
      <f:convertNumber integerOnly="true" groupingUsed="false" maxIntegerDigits="8" />
  </h:inputText>
  
  <a4j:commandButton id="btnInserirDizimista" value="Inserir" oncomplete="#{rich:component('pnlOk')}.show()" render="pnlMessages outPnlOk" actionListener="#{dizimistaMB.inserirDizimista}"/>
  
  <a4j:outputPanel id="outPnlOk" ajaxRendered="true">
  <rich:popupPanel id="pnlOk" modal="true" height="150">
          <h:graphicImage value="/images/info.jpg" />
          <h:outputText id="textoModalOk" value="#{dizimistaMB.textoModal}" />
          <h:commandButton value="OK" action="dizimista?faces-redirect=true"
              onclick="#{rich:component('pnlOk')}.hide(); return false;" >
              <a4j:ajax execute="formPnlOk" />
          </h:commandButton>
      </rich:popupPanel>
  </a4j:outputPanel>

      try{

When you render the contents of a rich:popupPanel through AJAX (rendering from a4j:commandButton), it may be best choose to display it conditionally using its show attribute, instead of calling Javascript code (oncomplete).

So, I suggest you just add a condition for showing the popupPanel. Assuming that textoModal is null upon initialization, and your bean is a request scoped, you can just use something like this:

<rich:popupPanel id="pnlOk" modal="true"
       show="#{dizimistaMB.textoModal != null}" ...>

_{You may want to create a method in the backing bean something like public boolean isShowTextoModal() that may implement better rules than simply checking if a field is not null.}

Then, you can change your button to this:

<h:commandButton id="btnInserirDizimista" value="Inserir"
       render="pnlMessages outPnlOk"
       action="#{dizimistaMB.inserirDizimista}" />

... and remove the ActionEvent argument from your method inserirDizimista, making it an action method instead of a actionListener.

This should get things going for you.
