    <p>In the following scenario, where I have several dataTables that I build iterating over a ui:repeat tag, I have experienced that row listener returns null for selected elements that are not in the first table.</p> <p>In order to understand the model object, I have several menus, and each of them contains several areas.</p> <p>Any help will be much appreciated.</p> <pre><code>&lt;ui:repeat value="#{someBean.menus}" var="menu"&gt; &lt;p:dataTable var="area" value="#{menu.areas}" rowKey="#{area.id}" selection="#{menu.area}" selectionMode="single"&gt; &lt;p:ajax event="rowSelect" listener="#{someBean.rowSelected}" /&gt; &lt;f:facet name="header"&gt;#{menu.name}&lt;/f:facet&gt; &lt;p:column&gt; &lt;f:facet name="header"&gt;&lt;/f:facet&gt; &lt;h:outputText value="#{area.id}" /&gt; &lt;/p:column&gt; &lt;p:column&gt; &lt;f:facet name="header"&gt;Area name&lt;/f:facet&gt; &lt;h:outputText value="#{area.name}" /&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; &lt;/ui:repeat&gt; public class Areas extends ListDataModel&lt;Area&gt; implements SelectableDataModel&lt;Area&gt;, Serializable { private static final long serialVersionUID = -9102592194300556930L; public Areas() { } public Areas(List&lt;Area&gt; data) { super(data); } @Override public Area getRowData(String rowKey) { @SuppressWarnings("unchecked") List&lt;Area&gt; areas = (List&lt;Area&gt;)getWrappedData(); for (Area area : areas) { if (String.valueOf(area.getId()).equals(rowKey)) { return area; } } return null; } @Override public Object getRowKey(Area area) { return area.getId(); } } public class Menus extends ListDataModel&lt;Menu&gt; implements SelectableDataModel&lt;Menu&gt;, Serializable { private static final long serialVersionUID = -4079772686830676202L; public Menus() { } public Menus(List&lt;Menu&gt; data) { super(data); } @Override public Menu getRowData(String rowKey) { @SuppressWarnings("unchecked") List&lt;Menu&gt; menus = (List&lt;Menu&gt;)getWrappedData(); for (Menu menu : menus) { if (String.valueOf(menu.getId()).equals(rowKey)) { return menu; } } return null; } @Override public Object getRowKey(Menu menu) { return menu.getId(); } } </code></pre> <p>...in the bean someBean</p> <pre><code>public void rowSelected(SelectEvent event) { Area selectedArea = (Area)event.getObject(); //This, is null for other tables except the first System.out.println("SELECTED AREA:" + selectedArea); //... } </code></pre>

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.
