Question

I have this code above which works perfectly when i select some of the items on him... The a4j:support works fine and rerender my another field correctly... The problem is if i choose one item, and then i back to "noSelectionLabel"... When i do this for some reason my a4j:support dont work, i dont get into my method "setarFormulario" and i dont rerender my another field...

<s:decorate template="layout/form.xhtml">
            <ui:define name="label">Evento:</ui:define>
            <h:selectOneMenu value="#{home.instance.evento}" required="true">
                <s:selectItems value="#{eventoService.obterTodos()}" var="evento" label="#{messages[evento.nome]}"  noSelectionLabel="#{messages[ br.com.message.NoSelection ]}" />
                <s:convertEntity  />
                <a4j:support event="onchange"  action="#{home.setarFormulario}" reRender="camposFormulario" ajaxSingle="true"  />
            </h:selectOneMenu>
        </s:decorate>

哪怕是选择不选的劳工,我怎么能够走进我的手法? 那么,我的家事就应该取消。

Answer 1

Yor field h:select OneMenu 然后需要选择noSelectionLabel数值,如果你有确认错误,那么action=”#{home.setarFormulario}"永远不会被称作。

作为你可以安排的工作:true。页: 1 那么,在选定价值时,诺森卡就会被隐藏起来。

Answer 2

<h:message f或="id of the selectonemenu component " ></h:message>
