    copied!<p>While Richfaces extended data tables support a <a href="http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=extendedDataTable&amp;sample=exTableSelection&amp;skin=blueSky" rel="nofollow">selection management</a>, Richfaces datatables don't.</p> <p>What I found the easiest way to do to retrieve a somehow selected item from a list, is to add an icon to every row. For this, put the command-Button into the data table itself:</p> <pre><code>&lt;rich:dataTable id="itemTable" value="#{backingBean.itemsList}" var="i" &gt; &lt;rich:column&gt; &lt;h:inputText id="myId" value="#{i.value}" /&gt; &lt;h:commandButton id="saveB" action="#{backingBean.doSave}" /&gt; &lt;/rich:column&gt; &lt;/rich:dataTable&gt; </code></pre> <p>In the bean code, provide the method <code>doSave</code> but with an additional parameter ´ActionEvent´</p> <pre><code>public String doSave(ActionEvent ev) { Item selectedItem = null; UIDataTable objHtmlDataTable = retrieveDataTable((UIComponent)ev.getSource()); if (objHtmlDataTable != null) { selectedItem = (Item) objHtmlDataTable.getRowData(); } } private static UIDataTable retrieveDataTable(UIComponent component) { if (component instanceof UIDataTable) {return (UIDataTable) component;} if (component.getParent() == null) {return null;} return retrieveDataTable(component.getParent()); } </code></pre> <p>You see, that the <code>ActionEvent ev</code> provides you with the source element <code>(UIComponent)ev.getSource()</code>. Traverse through it until you hit the <code>UIDataTable</code> element and use it's row data.</p> <p>Possible way two is to justgive the element as parameter with the function call:</p> <pre><code> &lt;rich:dataTable id="itemTable" value="#{backingBean.itemsList}" var="i" &gt; &lt;rich:column&gt; &lt;h:inputText id="myId" value="#{i.value}" /&gt; &lt;h:commandButton id="saveB" action="#{backingBean.doSave(i)}" /&gt; &lt;/rich:column&gt; &lt;/rich:dataTable&gt; </code></pre> <p>and in the bean </p> <pre><code>public String doSave(Item item) { // do stuff } </code></pre> <p>That's not as clean, but should work with the EL, too. Hope, it helps...</p>
