    <p>PF 3.5.10, Mojarra 2.1.21, JBoss 7.1.1, PE 7.1, Omnifaces 1.5</p> <p>I want to use datatable row editing in a p:Dialog. I have a datatable with a row editing in a Dialog. (Showcase: <a href="http://www.primefaces.org/showcase/ui/datatableRowEditing.jsf" rel="nofollow">http://www.primefaces.org/showcase/ui/datatableRowEditing.jsf</a>) If I click "OK" on the Dialog the changes should be saved, and if I click "Cancel" the changes will be dismissed. If row editing for a row is activated and I can change the values in a row, and then I click "Ok" on a Dialog, the active changes in a row will be lost. How can I retrieve an actual status of editing ? How can I know if a row in a datatable is currently edited ? If i know that I can warn User that the changes will be lost.</p> <p>Edit: link to PF sources <a href="http://grepcode.com/file/repository.primefaces.org/org.primefaces/primefaces/4.0-20130705.184420-2/org/primefaces/component/datatable/DataTable.java?av=f" rel="nofollow">Grepcode: PF sources isEditingRow()</a></p> <pre><code>&lt;p:dialog&gt; &lt;h:form&gt; &lt;p:tabView cache="false" id=.. binding=..&gt; &lt;p:tab&gt; &lt;p:dataTable binding=.. id=... widgetVar=... var=.. &gt; &lt;/p:dataTable&gt; &lt;/p:tab&gt; &lt;/p:tabView&gt; &lt;p:commandButton process="@form" action="myBean.listener()" value="OK" update="@form" onstart="anotherTable.filter()" /&gt; &lt;/h:form&gt; &lt;/p:dialog&gt; </code></pre> <p>Edit: I accepted the answer because I implemented the required feature myself. </p>

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.
