Async form validation

[frederikcreemers]

Sometimes, the client needs to communicate with the server in order to know wether the value of an input field is valid. For instance, usernames and e-mail addresses often need to be unique.

To allow this, I'd like to propose the following: When a $parsers element (from now on called a $parser, returns a value, we check wether it's a promise (both $q and native js promises). If it is, we apply a new 'processing' state to the form input. Then, then, when the resolve function is called, it receives the value you'd normally expect from a $parser.

I'm currently working on an implementation for this, but I'm new to the codebase, so it may take some time.

Hmm, I'm pretty sure I saw already an issue opened for this, can't find it atm, though...

Maybe you're thinking about my topic in angular-dev? I posted about this a
while ago, but never got to implement it.

I searched for it, but couldn't find it.
