    <p>If you're using <code>@ViewScoped</code> bean you could do the following changes:</p> <p>First change your <code>selectOpt1</code> method to type <code>void</code>:</p> <pre><code>public void selectOpt1() { this.list1Val = 1; this.list2Val = 1; //... } </code></pre> <p>Give an <code>id</code> to the component you want to update upon selecting items. I assume List 1 in this case:</p> <pre><code>&lt;h:selectOneMenu id="list1" value="#{MyClass.list1Val}"&gt; //... &lt;/h:selectOneMenu&gt; </code></pre> <p>And in your button, add an <code>f:ajax</code> tag that partially submits only that component for processing:</p> <pre><code>&lt;h:commandButton value="Select all opt1" action="#{MyClass.selectOpt1}"&gt; &lt;f:ajax execute="@this" render="list1" /&gt; &lt;/h:commandButton&gt; </code></pre> <p>If you plan to update multiple components, you may add their id separated by space:</p> <pre><code>&lt;f:ajax execute="@this" render="list1 list2" /&gt; </code></pre> <p>I hope it helps.</p> <p><strong>Edit</strong></p> <p>Well, sorry, I didn't noticed you're using JSF 1.x. In this case it wouldn't work.</p> <p>You could use a library such as <a href="http://www.jboss.org/richfaces" rel="nofollow noreferrer">RichFaces</a> to add ajax functionality though. Please, check out these topics:</p> <ul> <li><p><a href="https://stackoverflow.com/questions/12715731/ajax-behaviour-in-jsf-1-2">ajax behaviour in jsf 1.2</a></p></li> <li><p><a href="https://stackoverflow.com/questions/3545539/how-do-i-call-a-jsf-action-method-in-jsf-1-2-using-ajax">how do i call a jsf action method (in JSF 1.2) using Ajax?</a></p></li> </ul> <p><strong>RichFaces</strong></p> <p>As you mentioned you're using RichFaces you could switch the <code>f:ajax</code> tag to <code>a4j:support</code>:</p> <pre><code>&lt;h:commandButton value="Select all opt1" action="#{MyClass.selectOpt1}"&gt; &lt;a4j:support event="onclick" reRender=":list1" ajaxSingle="true" /&gt; &lt;/h:commandButton&gt; </code></pre> <p>Or like this using the <code>a4j:commandButton</code>:</p> <pre><code>&lt;a4j:commandButton value="Select all opt1" reRender=":list1" ajaxSingle="true" /&gt; </code></pre> <p>For more info on this behavior, please take a look at <a href="http://docs.jboss.org/richfaces/latest_3_3_X/en/devguide/html/ArchitectureOverview.html#d0e1166" rel="nofollow noreferrer">this</a>.</p> <p>Regards.</p>

    1. COhmmm... The bean is session scoped, but i'm working on **JSF 1.2** (for some reasons I've been unable to migrate to JSF 2.0 :(). Can this solution be adapted to my JSF version? Thanks!

    2. COWell, this wouldn't work for JSF 1.x. One option would be using a library such as RichFaces as this add ajax functionality. I've used it in the past and it's kind of easy to get started. See my edit.

    3. COThanks for the answer. It definetly was my fault, I didn't specify what technology I was using. And yes, I also use RichFaces and I work with `a4j:support`, but I can't solve the problem properly. Thank you for the related topic, I will study it.

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.
