Just to complicate things, you could actually implement chaining, but
it is more work.
1) Write a custom NavigationHandler
2) create some kind of "magic" syntax for chaining
3) Check in the NavigationHandler for the specified syntax
4) Invoke additional actions from the custom navigation handler
Something like this should work (BTW - I didn't check that this
compiles, I typed it from memory):
public class ChainingNavigationHandler
extends NavigationHandlerImpl
{
public final static String CHAIN_PREFIX = "chain-action:";
@Override
public void handleNavigation(FacesContext context, String fromAction,
String outcome)
{
if (outcome != null && outcome.startsWith(CHAIN_PREFIX))
{
String newAction = "#{" + outcome.substring(CHAIN_PREFIX.length()) + "}";
MethodBinding mb =
context.getApplication().createMethodBinding(newAction);
Object result = mb.invoke();
outcome = (result == null) ? null : result.toString();
fromAction = newAction;
}
super.handleNavigation(context, fromAction, outcome);
}
}
Then, from your action:
return ChainingNavigationHandler.CHAIN_PREFIX + "myBean.nextAction";

Yes, do what Andrew said. The code pattern will look something like:
public String firstAction() {
MyBean secondBean = getMySecondBean();
if(someCondition) {
return secondBean.secondAction();
}
}
