…ed template During it's linking phase, `ngView` relies on the info provided in `$route.current` for instantiating the initial view. `$route.current` is set in the callback of a listener to `$locationChangeSuccess`, which is registered during the instantiation of the `$route` service. Thus, it is crucial that the `$route` service is instantiated before the initial `$locationChangeSuccess` is fired. Since `ngView` declares `$route` as a dependency, the service is instantiated in time if `ngView` is present during the initial load of the page. Yet, in cases where `ngView` is included in a template that is loaded asynchronously (e.g. in another directive's template), the directive factory might not be called soon enough for `$route` to be instantiated before the initial `$locationChangeSuccess` event is fired. This commit fixes it, by always instantiating `$route` up front, during the initialization phase. Fixes angular#1213 Fixes angular#6812

Would be cool to get this fixed! Does this commit address the problems the first fix for this had? Namely that this caused lots of test failures in a google app because the order of some events changed? |
|
@Narretz, I'm not aware of the first fix you mention, but I'm quite confident, there won't be any issues with event order. This fix doesn't change the order of any events, it just ensures |

I found this comment: #1213 (comment) |
|
Ah, right, I forgot about that. No, this fix just ensures |
|
Ok, then it LGTM. |
