How to Render A Page From beginning(even if it was rendered)?

Question

Hi there,
our problem is like...
we use popup windows in our jsf ERP application to fill some fields of opener window,
like when we open the popup window, there are a few query fields and sorting part and datatable, selection fills the opener window's specific areas,
lets come to the problem, after querying and closing the window,when we want to reopen that popup it shows the old page, with datas inside it....
we solved the problem by resetting bean(session) in the page code and giving null values to the components in the components.
but we want to bring a global solution, we have lots of different popups like this, and all these popups are opening via javascript with a 'reset' parameter.
we want to render the page from beginning if it has 'reset' parameters.(this means if it was rendered before , render component tree from beginnin even if it exist)
we tried to do this at phaseListener before restroView, but failed.
any brilliant solution with code example?
regards

Answer 1

what i find as a solution , to check these pages in a phaseListener. but at which phase?
if u use before RestoreView u wont be able to get viewId , so it is better to check this at after RestoreView Phase,
I already eliminate other phases
Because I want only a fresh render from beginning so no need to tire the server for nothing.
so second problem how to distinguish the popup query windows from others
because i dont want this check to be done for every page:)
when we call these popup windoes we send a parameter that u can pick up anything useful for u, we use “reset” here, and u can pick this code inthe
public void afterPhase(PhaseEvent e) method.
FacesContext context=FacesContext.getCurrentInstance();
HttpServletRequest request = (HttpServletRequest)context.getExternalContext().getRequest();
if(request.getParameter(“reset”)!=null)
if(e.getPhaseId()==PhaseId.RESTORE_VIEW)
{ Application application = context.getApplication();
ViewHandler viewHandler = application.getViewHandler();
UIViewRoot viewRoot =viewHandler.createView(context,context.getViewRoot().getViewId());
context.setViewRoot(viewRoot);
}of course u have to register ur phase listener in your faces-config
nowww whenever one of the pages with “reset” paramater
it will be cleared and rendered in that way.
but opppps probably u will get data in ur datatable! Probably because u use session bean ,
u can sort this problem out doing like this
in the Getter method of ur bean instance,
check the “reset” parameter if it exists then
set ur bean null, then u wont have data in ur binded fields.
