    If we use fragments which can be put to stack then we have problems.
    Because of two conditions we are here:
    1.) Control is created for the first time
    2.) Fragment is paused and resuming...
    Question: Which value should be displayed in the user interface:
              valueFromScript or valueFromUser?
