    copied!<p>You should move your <code>h:form</code> to encapsulate the <code>p:commandButton</code>. That prevent your <code>p:commandButton</code> to submit anything to the bean. You should add it like this :</p> <pre><code>&lt;h:body&gt; &lt;h:panelGrid id="login-panel"&gt; &lt;h:form rendered="#{loginManagedBean.loggedClient eq null}"&gt; &lt;h:panelGroup id="loginPanelGrid"&gt; &lt;h:outputLabel for="username" value="Username:" /&gt; &lt;p:inputText value="#{loginManagedBean.username}" id="username" required="true" label="username" /&gt; &lt;h:outputLabel for="password" value="Password:" /&gt; &lt;p:password value="#{loginManagedBean.password}" id="password" required="true" label="password" /&gt; &lt;f:facet name="footer"&gt; &lt;p:commandButton id="loginButton" value="Login" update="login-panel" action="#{loginManagedBean.login(actionEvent)}"/&gt; &lt;/f:facet&gt; &lt;/h:panelGroup&gt; &lt;/h:form&gt; &lt;p:panelGroup rendered="#{loginManagedBean.loggedClient ne null}" id="okLoginPanelGrid"&gt; &lt;h:outputText id="clienteLogado" value="#{loginManagedBean.loggedClient.client_name}" /&gt; &lt;/p:panelGroup&gt; &lt;/h:panelGrid&gt; &lt;/h:body&gt; </code></pre> <p><strong>Not related :</strong></p> <p>I would also say the shorter a bean lives, the better your memory usage will be. In that way, the bean <code>LoginManagedBean</code> don't need to be <code>SessionScoped</code>, it could even be only <code>RequestScoped</code> if you move your property <code>loggedClient</code> to a SessionScoped attribute.</p>
