Uhm... as far as I know that's not true...

I think there are two clean approaches (I used both, in different
cases):
1) the dialog is ran in a loop, which always run()s it again when the
data validity check is no passed (possibly after showing an error
message)
2) the buttons are initially unsensitive and a function, which runs
several times per second and checks the validity, takes care of setting
them (un)sensitive
