JSF 1.2: How to keep request scoped managed bean alive across postbacks on same view?

by

I’ll assume that the session scope is not an option, otherwise this question makes little sense.

You can do it using Tomahawk <t:saveState>. Add the following line somewhere to the page:

<t:saveState value="#{bean}" />

RichFaces <a4j:keepAlive> does also the same:

<a4j:keepAlive beanName="#{bean}" />

Or if there is room, upgrade to at least JSF 2.x and put the bean in view scope:

@ManagedBean
@ViewScoped
public class Bean implements Serializable {
    // ...
}

Regardless of the way, the same bean will be there when you postback to the same view and keep returning null or void from action methods.
