    <p>I struggled for a whole week now and dont get it work. The user objects dont get updated... Here is the important xhtml part:</p> <pre><code>&lt;p:dataTable id="usersTable" var="user" value="#{userBean.allUsers}"&gt; &lt;p:ajax event="rowToggle" listener="#{userBean.onRowToggle}" update=":form_user_management:tabView_viewUsers:messages" /&gt; &lt;f:facet name="header"&gt; User &lt;/f:facet&gt; &lt;p:rowExpansion&gt; &lt;h:panelGrid id="display" columns="2" cellpadding="10" style="width:300px;" styleClass=" ui-widget-content grid"&gt; &lt;p:panel id="panel" header="Benutzer bearbeiten"&gt; &lt;p:messages id="msgs"/&gt; &lt;h:panelGrid columns="3" &gt; &lt;h:outputLabel for="firstname" value="Firstname: *" /&gt; &lt;p:inputText id="firstname" value="#{user.userFirstName}" required="true" label="Firstname"&gt; &lt;f:validateLength minimum="2" /&gt; &lt;/p:inputText&gt; &lt;p:message for="firstname" display="icon"/&gt; &lt;h:outputLabel for="surname" value="Surname: *" /&gt; &lt;p:inputText id="surname" value="#{user.userLastName}" label="Surname" required="true"&gt; &lt;f:validateLength minimum="2" /&gt; &lt;p:ajax update="msgSurname" event="keyup" /&gt; &lt;/p:inputText&gt; &lt;p:message for="surname" id="msgSurname" display="icon"/&gt; &lt;p:commandLink id="changepw" value="Passwort ändern" onclick="dlg.show()" title="Passwort ändern"&gt; &lt;f:setPropertyActionListener value="#{user}" target="#{userBean.currentUser}" /&gt; &lt;/p:commandLink&gt; &lt;p:commandButton ajax="true" id="btnUpdateUser" value="Update" update=":form_user_management @all" actionListener="#{userBean.updateUser(user)}"/&gt; &lt;p:commandButton ajax="true" id="btnDeleteUser" value="Delete" update=":form_user_management" actionListener="#{userBean.deleteUser(user)}"/&gt; &lt;/h:panelGrid&gt; &lt;/p:panel&gt; &lt;/h:panelGrid&gt; &lt;/p:rowExpansion&gt; </code></pre> <p> </p> <p>When I click on "Save" the expanded Row disappears, but the new values are not shown and the Java Method "userBean.updateUser(user)" gets only the old values of user object.</p> <p>The head of UserBean is:</p> <pre><code>@Named @SessionScoped public class UserBean implements Serializable { </code></pre> <p>SessionScoped is from the javax.enterprise.context</p> <p>I also tried to use the old @ManagedBean things, but that didnt help either. I think the problem is located in the xhtml file and with the ajax stuff... Oh, and I use and the other template stuff. </p> <p>Using Primefaces 3.4 and Glassfish 3+</p> <p>Full UserBean: <a href="http://pastebin.com/yQCgiM4E" rel="nofollow">http://pastebin.com/yQCgiM4E</a> Full Xhtml: <a href="http://pastebin.com/19TWt3Dv" rel="nofollow">http://pastebin.com/19TWt3Dv</a> (line 110 is the interesting thing)</p>

    1. COThere's a lot going on in that rowExpansion. Maybe even too much. You can start by slimming it down, adding `<p:messages autoUpdate="true"/>` to your view and changing `actionListener` to `action`

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
