Using richfaces's tabPanel - tab's ontableave

Using Seam 2.2.2.Final and Richfaces 3.3.3.Final.

I need to perform an action when user leaves a tab, and this action can only take place after all the page is loaded, there are some bean init taking place on each tab content. So I went and read about .

Problem is, with 3 tabs, for example, as each tab is rendered and render passes for the next one, the command is fired. No good, bean not initialized and I get nullpointer pointed at me!

Anyway to prevent this behavior on this tag? As I am doing an improvement on a very large app, I am trying to mess around the deployed code as little as possible.

Thankx in advance for taking a look. Here is an example code for my page:

<?xml version="1.0" encoding="ISO-8859-1"?>

                .
                .
                .

Best How To :

The @ontableave is for client-side code, i.e. JavaScript, not for bean methods. If you need to execute something on the server in response to a client-side event, use <a4j:support>:

<rich:tab label="Report" … >
    <a4j:support event="ontableave" 
                 action="#{sessionProcess.writeDraftReport()}" />
</rich:tab>
