AS3 - How to do a synchronous load of an asynchronous call?

Question

I have a function that loads a user object from a web service asynchronously.

I wrap this function call in another function and make it synchronous.

For exam

See my answer here:

DDD and Asynchronous Repositories

Flex and Flash Remoting is inherently asynchronous so fighting against that paradigm is going to give you a ton of trouble. Our service delegates return AsyncToken from every method and we've never had a problem with it.

If you want to ensure that the application doesn't render a new view or perform some other logic until the result/fault comes back, you could do the following:

1. Attach an event listener for a custom event that will invoke your "post result/fault code"
2. Make the async call
3. Handle the result/fault
4. Dispatch the custom event to trigger your listener from #1

Bear in mind this going to lead to a lot of annoying boilterplate code every time you make an async call. I would consider very carefully whether you really need a synchronous execution path.
