when you cancel the dialog, you're presented with the dialog again.
That's neither unexpected nor a side effect. Canceling a dialog has the same
effect as calling "error number -128." So your first "invalid" dialog
displays, you hit cancel, it throws error -128, which your "on error" block
catches and then displays the same dialog again. Being able to catch dialog
cancellations is a feature, not a bug. To get the dialog only once, you might
change the first call to "error" instead.
