Abort from page callback function
A slighly odd problem: There is a lot of information on
how Abort can be used in page callback functions to prevent
showing or leaving the page. What if I encounter a situation
where I actually want to abort the installer?
Moving all tests to .onInit works, but it would be so
much nicer to display the Welcome screen first. Also, it
may not always be possible when the test depends on some
selection made by the user in a page.
So, is there a way to either
1. abort the installation from a callback function or
2. otherwise execute some code between pages?
I'm using MUI2, BTW.
