对话框InputText Primefaces jsf的错误验证

Question

I have a DataTable and edit a listing you have to open the Dialog component with the respective values ​​that sends the selected object from the DataTable , but cannot open. I have noticed that the function is REQUIRED = "true" and also that no error is displayed, the only solution that helped me erase the function is REQUIRED .

How do I to bring up the Dialog component without taking the REQUIRED function. An example of the code:

<p:tab id="tab_listar" title="#{msg.labelListar}">
    <h:form id="form_mostrar_listado">
        <p:dialog id="ModificarLugar" header="Modificar Datos" widgetVar="LugarDialogo2"
                  modal="false" resizable="false" hideEffect="bounce" showEffect="explode">
            <h:panelGrid id="ModificarLugar1" columns="2" cellpadding="5">
                <h:outputText value="#{msg.labelCodigo}"/>
                <h:outputText value="#{BeanLugar.objLugarMod.cod_lugar}"/>
                <h:outputText value="#{msg.labelNombre}"/>
                <p:inputText value="#{BeanLugar.objLugarMod.nombre}" id="nombre_lu_mod"
                             required="true" requiredMessage="#{msg.labelNoVacio}"
                             validatorMessage="#{msg.labelNoValido}"> </p:inputText>
                <h:outputText value="#{msg.labelUbicacion}"/>
                <h:panelGroup>
                    <p:selectOneMenu value="#{BeanLugar.objLugarMod.objPais.cod_pais}"
                                     required="true" id="cod_pais_mod" effect="fade"
                                     requiredMessage="#{msg.labelNoVacio}"
                                     validatorMessage="#{msg.labelNoValido}">
                        <f:selectItem itemLabel="#{msg.labelEligePais}" itemValue=""/>
                        <f:selectItems value="#{Pais.cargarComboPais}"/>
                    </p:selectOneMenu>
                    <h:message showDetail="false" showSummary="true" for="cod_pais_mod"/>

Answer 1

You are processing all form so JSF tries yo validate all components with required true. You have to tell commandLink what you want to process, for example:

 <p:commandLink title="Editar" action="#{BeanLugar.editarLugar(ls)}"
                                   value="Editar"
             update=":LugarTabView:form_mostrar_listado:ModificarLugar"
                                    oncomplete="LugarDialogo2.show()"
   process="resListadoLugar"> // or the path of the component you want to process
  </p:commandLink>
