How to reset the view during RESTORE_VIEW phase

[Davie Lin]

Hi everyone, once again, I got myself into some weird situation again. Thanks for your patience.

my page has a form that user can do search on a database table. My dataTable column begin with Delete and Edit button. My backing bean are in request scope. I have to use <a4j:keepAlive> in order for my Delete and Edit button to function correctly. However, my question here is, let's say I just do a search and I click the home page link and come back to my search page again. The <a4j:keepAlive> tag kept the last table I searched. Of course, when I commented out the <a4j:keepAlive> tag, my last search will not be there but than my Edit and Delete button won't work. I was wondering what method in FacesContext can I use to clear it and where should I place it? I have tried something like the following in my bean's <init>()

  
FacesContext context = FacesContext.getCurrentInstance();
    Application application = context.getApplication();
    ViewHandler viewHandler = application.getViewHandler();
    UIViewRoot viewRoot = viewHandler.createView(context, context
     .getViewRoot().getViewId());
    context.setViewRoot(viewRoot);
    context.renderResponse();

and I got an exception that says, I have a duplicate id frm1:_id22

Still have yet to come up with any promising solution. Hope someone can help, thanks again
