<p>Richfaces 3.2.0.GA and XHTML as mark up</p> <p>You can use javascript to call an a4j:js method, which inturn calls action method from managed bean. The param which you need to pass can be set to a hidden variable which when set will set the value to the java variable in your bean.</p> <pre><code><script> function onButtonClick(){ $("#yourValue").val("value"); actionListenerMethod(); } </script> <a4j:jsFunction name="actionListenerMethod" actionListener="#{yourManagedBean.actionMethod}" oncomplete="scriptOnComplete();"> </a4j:jsFunction> <h:inputHidden id="yourValue" value="#{yourManagedBean.yourValue}" /> </code></pre> <p><strong>Managed bean:</strong></p> <pre><code>public void actionMethod(ActionEvent event){ if(yourValue == "something"){ /*your action goes here*/ } } </code></pre> <p>Otherwise you can by-pass this hidden variable by use of action param</p> <pre><code><script> function onButtonClick(){ actionListenerMethod("value"); } </script> <a4j:jsFunction name="actionListenerMethod" actionListener="#{yourManagedBean.actionMethod}" oncomplete="scriptOnComplete();"> <a4j:actionparam name="param1" assignTo="#{yourManagedBean.yourValue}" /> </a4j:jsFunction> </code></pre> <p>In the later case the action param might get set only after the manged bean gets completed, in this case you can use Action atribute to call your action method instead of an action listener. This will help you to set the param and then call the action method.</p> <pre><code><a4j:jsFunction name="actionListenerMethod" action="#{yourManagedBean.actionMethod}" oncomplete="scriptOnComplete();"> <a4j:actionparam name="param1" assignTo="#{yourManagedBean.yourValue}" /> </a4j:jsFunction> </code></pre>

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.
