Of course, now you might have to deal with checking for null, as Jesse Warden complaint about already. A solution to this problem could be to return a default value instead of null. Of course, this […]

– try/catch to capture all errors inside my class(es)
– never use throw again. Instead, dispatch an error event that abstracts all errors into one event.
– have that error event include the reason why something broke

If you code ActionScript, you understand events. Events are optional, just like RuntimeExceptions (unchecked exceptions) in Java. So… seems good enough for me! Heck, even HTTPService does this via the fault event. No exceptions there… good enough for Flex, good enough for me.

Checked exceptions is still something that people aren’t sure about in Java. The fact that C# chose not to have them brought a lot of discussion a few years ago. There’s a lot of good articles on this: see http://www.mindview.net/Etc/Discussions/CheckedExceptions

The strangest thing to me with exceptions is something small, which is that binding swallows a few exception (see BindingUtil). That’s caught me a few times.
