Basically there are couple pages which use the same custom controller (no extensions), it's kinda wizard.
When navigating between pages, i.e. clicking next/previous buttons, view state is preserved, everything works as expected. But for some reason after every click url in the browser is changed.
That's why we have an issue when user click browser's refresh button in the middle of the wizard, it just tries to refresh bad url. And yes, set redirect is set to false and we are using the same controller for all wizard pages (double checked).
Maybe someone from the community has already encountered with such problem (or maybe even solved it). Any help would be appreciated how to keep the same url in browser.
Thanks in advance.
