Here we are studying the connection between two pages
therefore we need to create two page fragments.

At the components panel search 'panel box' then drag and drop a panel box
onto the page fragment. 

Then drag and drop a button from the panel 'General Controls'.

You can change the names of the button and the panel box at
the 'Common' tab.

Then go to page flow in web content (in Applications tab) and create a
ADF Task Flow.

Drag and drop the two page fragments you created earlier on to the
ADF Task Flow. The fist page is highlighted in green while the other is not.

Select Control Flow Case from Components tab and draw arrows from
one page to the other, it shows the way that the buttons work when clicked.

Then go to a page fragment you created before and tap on the
button once. Then from the Button.next.properties tab you
need to change the action of the button.

Select Edit.

Change the scope name to pageFlow and press 'Ok'.

Then add a Method name

 Then go to a page fragment and double click on the button.

Change return NULL to the String you provided for the control flow lines,
 the name must be within double cotes("") because it's a String
