Two questions about page sequence.

Hi There!

Is there a way to go back on the page sequence using a function?
This is needed to prevent that nothing is selected in the components page. I use MUI.

!ifdef Show_ComponentsPage
!insertmacro MUI_PAGE_COMPONENTS
Page custom CheckSelection # GOBACK????
!endif


Can I detect if somebody pressed the back button?
Sometimes I create an error message at the end of a page. But if somebody press the back button this error message should not appear. Can I detect this?

Cheers
Gabriel

1. Maybe this archive page help you to go to specified page.
2. At the pre-function of next page you can define variable. And if user pressed back-button - you always know it.

This helps a lot. Thank you. :-)
