Unsolved QtInstaller framework - "Back" button retain previous selections
I am using QtInstaller to make an installer. There is a "Back" button on each screen and that's useful. When I would make some selection on Screen A, proceed "Next" to Screen B and then decide to go back to Screen A to alter my selection, the first time value on my selection is cached somewhere and second time value for the selection is not being honored.
I could not find out how to "Clear selection" when "Back button" is pressed. Is there such an capability? If so, how do I express that within QtInstaller framework?
