    <p>I have an existing working Primefaces 2 MenuBar with the MenuItems defined as follows:</p> <pre><code>&lt;p:menubar style="width:625px" autoSubmenuDisplay="true"&gt; &lt;p:submenu label="#{messages.label_home}"&gt; &lt;p:menuitem value="#{messages.label_logout}" url="#" icon="ui-icon ui-icon-close"/&gt; &lt;/p:submenu&gt; &lt;p:submenu label="#{messages.label_cockpit}"&gt; &lt;p:menuitem value="#{messages.label_create}" action="#{cockpitMenuBean.displayCreateDialog}" icon="ui-icon ui-icon-document" ajax="false"/&gt; &lt;p:menuitem value="#{messages.label_list}" action="#{cockpitMenuBean.displayList}" icon="ui-icon ui-icon-folder-open" ajax="false"/&gt; &lt;/p:submenu&gt; </code></pre> <p>I want to move the menu model from the xhtml to a backing bean as follows:</p> <pre><code>&lt;p:menubar style="width:625px" autoSubmenuDisplay="true" model="#{cockpitMenuBean.menuModel}"/&gt; </code></pre> <p>The problem and my question is centered on the <code>action</code> attribute above.</p> <p>The CockpitMenuBean.displayCreateDialog() returns a string</p> <pre><code>public String displayCreateDialog() { cockpitMenu = new CockpitMenu(); createDialogVisible = true; return "cockpitMenu"; } </code></pre> <p><code>menuItem.setAction(arg);</code> which seemed like it should be the same as the <code>action</code> attribute in the XHTML is looking for arg to be a <code>MethodBinding</code> which is deprecated.</p> <p><code>menuItem.setActionExpression(arg)</code> is next most likely since the string in the XHTML is an EL expression <code>#{cockpitMenuBean.displayCreateDialog}</code>, but that just returns a String. </p> <p><code>menuItem.setActionListener(arg)</code> is deprecated.</p> <p>I am not connecting the dots in moving from the XHTML to the backing bean in building the menuitems that correspond.</p> <p>I tried:</p> <pre><code>MenuItem item1 = new MenuItem(); item1.setValue("Should be first"); item1.setUrl("#"); MethodExpression aEx = expFact.createMethodExpression(elCtx, "#{cockpitMenuBean.displayCreateDialog}", String.class, new Class[0]); item1.setActionExpression(aEx); menuModel.addMenuItem(item1); </code></pre> <p>And the menu item displays but nothing happens when I select it.</p>

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.
