I have wizard, which runs in conversation. User goes through pages and fill additional values. Problem occur when user press BACK button a goes to previous page then change some value and then press submit. Values in corresponding form don't change according to html inputs. In form stays values from first step.
Plot:
HTML page 1
- user fill 'Hello'
- submit
HTML page 2
- browser back
HTML page 1
- change input to 'Good bye'
- submit
HTML page 2
- in form stays first input 'Hello'
