    <p>JFS1.2 + Richfaces 3.3</p> <p>Situation is as follows:</p> <p>JSP page renders conditionally one or another panelGroup.</p> <p>Within each panelGroup there are couple setters and one command button. Each of two panelGroups uses own bean for setting and performing action.</p> <p>On the top of a page there's selectOneRadio with (obvious) two items - coresponding tow options of conditional rendering.</p> <p>Page renders properly, switcher causes to render appropriate panel. Case is, commands buttons doesn't call an action.</p> <p>I know what's going on - when I click a button to call action dom is regenerated, but the value that hold my decision to display particular panel doesn't exist anymore. The button is not recreated, action is not fired.</p> <p>Technically:</p> <pre><code>&lt;h:selectOneRadio value="#{reportType}"&gt; &lt;f:selectItem itemLabel="x" itemValue="x"/&gt; &lt;f:selectItem itemLabel="y" itemValue="y"/&gt; &lt;a4j:support event="onclick" reRender="xPanel, yPanel/&gt; &lt;/h:selectOneRadio&gt; &lt;h:panelGrid id="xPanel "columns="2" rendered="#{reportType eq 'x'}"&gt; &lt;...some setters&gt; &lt;... commandbutton&gt; &lt;/h:panelGrid&gt; &lt;h:panelGrid id="yPanel "columns="2" rendered="#{reportType eq 'y'}"&gt; &lt;...some setters&gt; &lt;... commandbutton&gt; &lt;/h:panelGrid&gt; </code></pre> <p>Question is, how to design the page to obtain proper rendering and actions? For now, I created additional session bean that holds switching value (x|y), but that desing smells bad for me...</p>

    1. COI think this a classical example of the not enough scopes in `JSF 1.2`. Everything greater than `request` must be `session`... `JSF 2.0` is much better:)

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.
