    <p>I'm using JSF 1.2 and RichFaces 3.3, I have a page called NewsItemDetails with the following structure</p> <pre><code>&lt;h:form&gt; &lt;h:panelBar&gt; &lt;h:panelBarItem&gt; &lt;myTag:searchModule /&gt; &lt;/h:panelBarItem&gt; &lt;/h:panelBar&gt; &lt;/h:form&gt; </code></pre> <p>and the backing bean of that page is of a request scope, and here is a snippet of the faces-config.xml:</p> <pre><code>&lt;managed-bean&gt; &lt;managed-bean-name&gt;newsItemDetails&lt;/managed-bean-name&gt; &lt;managed-bean-class&gt;class.location...&lt;/managed-bean-class&gt; &lt;managed-bean-scope&gt;request&lt;/managed-bean-scope&gt; &lt;managed-property&gt; &lt;property-name&gt;id&lt;/property-name&gt; &lt;value&gt;#{param['id']}&lt;/value&gt; &lt;/managed-property&gt; &lt;/managed-bean&gt; </code></pre> <p>And to be complete here's a snippet of the searchModule tag:</p> <pre><code>&lt;ui:composition&gt; &lt;rich:tabPanel&gt; &lt;rich:tab label="Images"&gt; &lt;h:panelGrid columns="2"&gt; &lt;h:inputText value="#{newsItemDetails.searchLabel}" /&gt; &lt;a4j:commandButton value="Search" actionListener="#{newsItemDetails.onSearch}" reRender="mediaItemsSearchResults, imagesDataTable" /&gt; &lt;/h:panelGrid&gt; &lt;a4j:outputPanel id="mediaItemsSearchResults" ajaxRendered="true"&gt; &lt;rich:dataTable id="imagesDataTable" value="#{newsItemDetails.searchResults}" var="image"&gt; &lt;h:column&gt; &lt;h:outputText value="#{image.title}"/&gt; &lt;/h:column&gt; &lt;/rich:dataTable&gt; &lt;/a4j:outputPanel&gt; &lt;/rich:tab&gt; &lt;/rich:tabPanel&gt; &lt;/ui:composition&gt; </code></pre> <p>Now the problem is, whenever I hit the search button, the action listener is never called, but I could see a request sent to the server through Firebug. And here's the strange thing if I call the same searchModule tag, just outside the rich:panelBarItem and I hit the search button the action listener is called, but the dataTable is not re-rendered, and it's only called the first time I hit the button.</p> <p>So if anyone has a clue why this is happening, I would be more than grateful. </p> <p>Thanks in advance</p>

    1. COIs the panelBarItem rendered by default when you enter the page for the first time? Why are you using a h:commandButton instead of a a4j:commandButton if you want to do an ajax call? (the reRender attribute doesn't make sense in a h:commandButton).

    2. COThe panelBarItem has a condition but by default is rendered, and regarding the h:commandButton, I'm actually using a4j:commandButton, but it was a typo

    3. COThe only thing that I can thik of that could stop the actionListener from being called is that commandButton is not rendered in the restoreView phase. Try changing the scope of the backing bean from request to session. If this fix it, then the problem is that something that contains the commandButton is not considered to be rendered in the restoreView phase.

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.
