ADF: showPopupBehavior operation & load trigger

Sometimes I need to dual authenticate the entrance of a page that contains a very sensitive information such Payroll page.

In my old days I implement such a case by developing a page to open it as dialog and handle the load in page phase listener life cycle.

Now I will introduce a more easer and professional mechanism for such a case, by opening a popup in page load in a simple way.

Project structure is an ADF fusion application, and ADF web project as the following:

With ADF Faces it's so easy to open a popup on page load. All what I needs to do is to define af:showPopupBehavior operation for af:document tag.

Note: af:showPopupBehavior trigger type should be set to load.
There are a lot of triggers for this operation could be found in "Oracle® Fusion Middleware Web User Interface Developer's Guide for Oracle ADF 11g R2(11.1.2.1.0)" usage and implementation.

This will ensure, it will be executed during document load and will call popup during page rendering phase:

The payroll.jsf page code is as the following:

When you run the application Popup is popped up on page load:
