    copied!<p>I am Using JSF 2 and EJB 3.1 to create a form.</p> <p>I am using this part of the page to get me some data, so I can pass it to my bean using the confirmDialog just below</p> <pre><code>&lt;p:column headerText="#{bundle.edit}" style="width:10px; overflow:visible;"&gt; &lt;p:rowEditor/&gt; &lt;/p:column&gt; &lt;p:column headerText="#{bundle.delete}" style="width:10px; overflow:visible;"&gt; &lt;p:commandButton update=":form" oncomplete="confirmation.show()" image="ui-icon ui-icon-close" title="Delete"&gt; &lt;f:param value="#{user}" name="userAction" /&gt; &lt;/p:commandButton&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; &lt;p:confirmDialog message="Are you sure? user:#{param['userAction']} " width="500" header="Confirm" severity="alert" widgetVar="confirmation"&gt; &lt;p:commandButton value="Yes sure" update=":form" actionListener="#{userController.deleteAction(param['userAction'])}" oncomplete="confirmation.hide()" /&gt; &lt;p:commandButton value="Not yet" onclick="confirmation.hide()" type="button" /&gt; &lt;/p:confirmDialog&gt; &lt;/h:form&gt; </code></pre> <p>And this is the Bean that should get it</p> <pre><code>@Named(value = "userController") @Stateful @RequestScoped @TransactionManagement(TransactionManagementType.CONTAINER) public class UserController implements Serializable { private User current; @Inject private br.com.cflex.itm.dataaccess.UserFacade userFacade; public UserController() { } public void deleteAction(User user) { userFacade.remove(user); } </code></pre> <p>But My bean is only receiving null as User, and <strong>in the Dialog I am printing the data so I can see there is a User Object selected there.</strong></p> <p><strong>What is wrong in passing params like that ?</strong><br> <strong>Why am I getting null in my Bean?</strong> Because they are getting lost in the communication between client and server-side...</p>
