form submission behaviour

Question

I would like to understand the behaviour behind a4j on Richfaces.

I have a h:form with a h:inputText and a a4j:commandButton. The button action call a method in my bean, and the oncomplete shows Richfaces.showModal with some content.

<h:form id="i_form">
    <h:inputText value="#{ordemManagedBean.formEntity.emissor.cpf}" required="true" />
    <a4j:commandButton value="#{msg.labelbtn}" reRender="f_FormordemEmissorModal" oncomplete="Richfaces.showModalPanel('ordemEmissorModal');" action="#{ordemManagedBean.consultarCadastroEmissor}" />
</h:form>

Outside h:form I have an ui:decorate that imports my Modal, which have a form around.

<ui:decorate template="/templates/ordemEmissorModal.xhtml">
        <ui:param
            name="beanForm"
            value="#{ordemManagedBean}"
/>

The problem: When I submit my form on button click, the method is fired and the modal is shown, but it works only at the first time. When I close my Modal, change the input value and submit, the method is not called and my modal is shown with the old content. What's happening in my second form submission?

Thank you in advance!

are you sure there is no validation error on the second form submit? — Ellie Fabrero, Aug 09 '12 at 02:13
Ellie, I tried using immediate=true on button and it is allways called! so im sure that is an validation error which is blocking this request. the question is: how can I list validation erros at this moment? — rodrigocprates, Aug 09 '12 at 12:54

To check for validation error you can use <h:message> or <h:messages> and supply the id of your <h:inputText> on the for attribute and reRender the <h:message> when the request is fired, and since you are using richfaces there is also <rich:message> or <rich:messages>, the functionality is the same but the the later has more additional features.

<h:form id="i_form">
    <h:inputText id="input" value="#{ordemManagedBean.formEntity.emissor.cpf}" required="true" />
     <rich:message for="input" id="error" />
    <a4j:commandButton value="#{msg.labelbtn}" reRender="f_FormordemEmissorModal, error" oncomplete="Richfaces.showModalPanel('ordemEmissorModal');" action="#{ordemManagedBean.consultarCadastroEmissor}" />
</h:form>

cool, but even using this approach I cannot see any validation message! I saw that it has a rendered attribute in input which is setted to true at second click. could be a problem? – rodrigocprates Aug 10 '12 at 17:49
it works! but how could I use an attribute (which supports EL) for hide, like 'rendered'? – rodrigocprates Aug 13 '12 at 12:54
you could wrap your h:inputText with a4j:outputPanel then use the rendered attribute there for hiding your h:inputText. – Ellie Fabrero Aug 14 '12 at 00:53
but the problem is when its not rendered, the input value is not sent with the form and so action is not called! – rodrigocprates Aug 17 '12 at 13:44
what error validation does it say when you set the rendered attribute to true? Maybe that's why the action is not called. – Ellie Fabrero Aug 18 '12 at 00:43
try using rich:messages and h:messages to get all the validation errors on your page. – Ellie Fabrero Aug 22 '12 at 01:06
