Use case : We have a jspx page welcome.jspx. We have to call a custom method(onPageLoadWelcome) before loading the jspx page.
Approach 1: Work with Event.
fig: jspx page
private void
onPageLoad(PhaseEvent phaseEvent){
System.out.println("Called onPageLoad by Neelmani");
}
fig: onPageLoad method as the part of Backing Bean
fig: OutPut
NOTE: Some times afterPhase() and beforePhase() will get executed multiple times. How to restrict them?
Solution:
public void beforePhase(PhaseEvent phaseEvent){
if(phaseEvent.getPhaseId().toString().equalsIgnoreCase("RENDER_RESPONSE 6")){
onPageLoad();
}
}
public void onPageLoad(){
System.out.println("onPageLoad");
}
Approach 2: Write the custom method, create Datacontrol and call it onPageLoad
Fig : Created an Interface with the method declaration onPageLoadWelcome()
Fig : Created the implementation class for the Interface
Fig : Extends the implementation class
Fig : Created the Data Control from the implementation class
Fig : Data Control of that implementation class
Fig : Create a method binding under the welcome page
Fig : Action Binding Dialog under the welcome page
Fig : Invoke Action Dialog under the welcome page
Fig : Invoke Action Property Dialog under the welcome page
Fig : Run the welcome page
Fig : Method got called before page load: the welcome page
