onEnter is called twice if a parameter is an array with more than one element

[realityking]

This seems to be a regression and currently stops us from updating to 0.2.11.

Plunkr: http://plnkr.co/edit/PmwRrdSMnlAetItQBeBl?p=info

The issue only occurs und the following conditions:

1. The parameter is a query parameter
2. The parameter is an array
3. The array contains more than one element

If you need any more information I'd be happy to help. I digging trough the callstack for both calls, and they seem to come form completely different places. I'm not familiar enough with the inner workings of UI Router to make any sense out of the behavior I saw.

You're seeing this:
* BREAKING CHANGE: state parameters are no longer automatically coerced to strings, and unspecified parameter values are now set to undefined rather than null.

The params code got a major overhaul in 0.2.11. You were relying on the array being coerced to a String.

You can now implement your own typed params, and could create an array type.
http://angular-ui.github.io/ui-router/site/#/api/ui.router.util.$urlMatcherFactory
http://angular-ui.github.io/ui-router/site/#/api/ui.router.util.type:UrlMatcher
http://angular-ui.github.io/ui-router/site/#/api/ui.router.util.type:Type

However, from what I can tell, it looks like query search params can not be typed. Hmmm... @nateabele is this by design?

I need to do some more research, stay tuned. https://github.com/angular-ui/ui-router/blob/master/src/urlMatcherFactory.js#L143

@christopherthielen Nope. Weird. Btw, I had a quick poke at this. It looks like the whole resolved promise actually gets resolved twice. Sigh... soon.

[christopherthielen]

I'll take this, I need to get familiar with the typed params anyway.

[christopherthielen]

I've got a bunch of Type fixes in a private branch. Here's a working plunk.

@nateabele I have about 6 commits to review with you. You can see the cumulative codebase with all the commits at https://github.com/christopherthielen/ui-router/tree/default-type-coersion

[realityking]

Anything I could do to help move this along?

[christopherthielen]

@realityking, thanks for the offer . I have a few more things to clean up related to Type(s) before I push this. 0.2.12 should come shortly after that.

[realityking]

Alright. I'll test this in our app after this is merged (and hopefully before the release).

[christopherthielen]

@realityking please build from master and test

Works perfectly. Thank you!
