    <p>I have followed this link in using the selection of mutiple values in p:datatable</p> <p><a href="http://www.primefaces.org/showcase/ui/datatableRowSelectionRadioCheckbox.jsf" rel="nofollow">http://www.primefaces.org/showcase/ui/datatableRowSelectionRadioCheckbox.jsf</a></p> <p>Now when i select mutiple values from it and click on the button in my form it should call a method in the bean which is working fine.But the selected values list is empty. I read the posts here and oucld not figure out the solution.I also tried different ways but did not work out.</p> <p>JSF Code:</p> <pre><code>&lt;p:dataTable value="#{deviceController.devicesModel}" var="deviceList" widgetVar="deviceTable" selection="#{deviceController.selectedDevices}&gt; &lt;p:column sortBy="#{deviceList.manufacturerSerialNum}" filterBy="#{deviceList.manufacturerSerialNum}"&gt; &lt;f:facet name="header"&gt; &lt;h:outputText value="Manufacturer Serial No"/&gt; &lt;/f:facet&gt; &lt;h:outputText value="#{deviceList.manufacturerSerialNum}" /&gt; &lt;/p:column&gt; &lt;p:column selectionMode="multiple"&gt; &lt;f:facet name="header"&gt; &lt;h:outputText value="#{bundle.ListLaptopTitle_inService}"/&gt; &lt;/f:facet&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; &lt;p:commandButton action="#{deviceController.update(deviceController.selectedDevices)}" value="Submit Request" style="margin-top: 20px"/&gt; </code></pre> <p>Code in Bean:</p> <p>public String update(List updateDevice) {</p> <pre><code> try { for(Device d:updateDevice) { getFacade().edit(d); } //message which indiactes device update is successful return "/example.html"; } catch (Exception e) { //handling exception return null; } } </code></pre> <p>So from the page I am passing the value of deviceController.selectedDevices which is empty when checked.</p> <p>Thanks</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.
