    <p>JSF generates HTML. JS/Ajax works on HTML. JS/Ajax updates HTML elements by finding it in HTML DOM tree by <code>document.getElementById()</code> and replacing its contents based on Ajax response. However, if a JSF component is instructed to not render HTML, then JS/Ajax cannot find it in the HTML DOM tree and thus can't replace anything.</p> <p>You can only ajax-update the HTML representation of a JSF component which is <strong>always</strong> rendered. So, wrap them in e.g. a <code>&lt;h:panelGroup&gt;</code>.</p> <pre><code>&lt;h:selectOneRadio ...&gt; &lt;f:ajax ... render="selectAndInputBox" /&gt; &lt;/h:selectOneRadio&gt; &lt;h:panelGroup id="selectAndInputBox"&gt; &lt;h:selectOneMenu ... rendered="..." /&gt; &lt;h:inputText ... rendered="..." /&gt; &lt;/h:panelGroup&gt; </code></pre> <h3>See also:</h3> <ul> <li><a href="https://stackoverflow.com/questions/9010734/why-do-i-need-to-nest-a-component-with-rendered-some-in-another-component-w/">Why do I need to nest a component with rendered=&quot;#{some}&quot; in another component when I want to ajax-update it?</a></li> </ul> <hr> <p><strong>Unrelated</strong> to the concrete problem, that <code>getIsType1()</code> method is clumsy. Just do the comparison directly in the view so that you can get rid of it.</p> <pre><code>&lt;h:selectOneMenu ... rendered="#{testBean.type == 'type1'}" /&gt; &lt;h:inputText ... rendered="#{testBean.type != 'type1'}" /&gt; </code></pre> <p>or perhaps, more matching your initial question,</p> <pre><code>&lt;h:selectOneMenu ... rendered="#{testBean.type == 'type1'}" /&gt; &lt;h:inputText ... rendered="#{testBean.type == 'type2'}" /&gt; </code></pre>

    1. COOk, thanks BalusC. I tried what you explained but it's still not working. I also changed according to your unrelated remark. I add a sysout on the setter and getter of 'type'. So I have 6 times 'getType : type1' when I start the application (why 6 times ?) but nothing else more when I select another type.

    2. COIs an ajax request been sent or not? Debug the HTTP traffic. As to 6 times being called, see http://stackoverflow.com/questions/4281261/why-is-the-getter-called-so-many-times-by-the-rendered-attribute/4281608#4281608 This shouldn't harm if you aren't doing any business logic in there.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
