I have 2 managed beans(one for the main JSF page and one for the one opened in a popup which opens on clicking on a link on the main page).
I can minimize the popup and do actions on main page.
I need to check if the main page has changed whenever i submit on the popup. Both backing beans are in request scope.
What is the way to do it? At every submit I should be able to find out if my main page has changed and throw an error.
