Notes:

• In scenario 1 other tables in the wizard (on the "Parameters" and "Output data" pages) should be treated in the same way.
• In scenario 2 the dialog with the message should appear on any page of the wizard if some data were modified only, i.e. if there were no modification, just close the wizard!
• Both element creation and editing should be tested.
