Maybe you’re googling to find the Flex View Navigator change event? I know I was but I didn’t find it. Here’s the quick fix:
You can watch for the length to change like this:
ChangeWatcher.watch(mainNavigator,’length’, mainNavigator_lengthChangeHandler, false, true);
Take note that we’re using weak reference here.
Another option that I’m leaning towards is responding to the view navigator’s elementAdd and elementRemove events.
Some of these blog posts are just so I can find the answer to the same problem later. But I hope they help someone else also
Best of luck,
