Is it possible to support routable engines?

What are the issues you're seeing when trying to use it in combination with routable engines?

What i am seeing is the following error

Assertion Failed: [ember-crumbly] Could not find a current route Error at assert (http://localhost:4200/assets/vendor.js:20974:13) at assert (http://localhost:4200/assets/vendor.js:32725:34) at Class.get (http://localhost:4200/engines-dist/authoring/assets/engine-vendor.js:5072:9) at ComputedPropertyPrototype.get (http://localhost:4200/assets/vendor.js:32381:28) at Object.get (http://localhost:4200/assets/vendor.js:37374:19) at RootPropertyReference.compute (http://localhost:4200/assets/vendor.js:30337:26) at RootPropertyReference.value (http://localhost:4200/assets/vendor.js:30204:45) at ArrayIterable.iterate (http://localhost:4200/assets/vendor.js:29960:26) at IterationArtifacts.isEmpty (http://localhost:4200/assets/vendor.js:59895:58) at IterablePresenceReference.value (http://localhost:4200/assets/vendor.js:64296:36)

Ill try to dig a bit more to get some more information.

Looks like in bread-crumbs.js

currentRouteName: readOnly('applicationRoute.controller.currentRouteName'),

currentRouteName is undefined since controller is pretty much empty. This described case is where I have put crumbly inside a component within my Ember Engine.

If i try to move the breadcrumb to the parent applications i get:

[ember-crumbly] route:authoring was not found Error at assert (http://localhost:4200/assets/vendor.js:20974:13) at assert (http://localhost:4200/assets/vendor.js:32725:34) at http://localhost:4200/engines-dist/authoring/assets/engine-vendor.js:5134:9 at Array.map (native) at Class._lookupBreadCrumb (http://localhost:4200/engines-dist/authoring/assets/engine-vendor.js:5126:44) at Class.get (http://localhost:4200/engines-dist/authoring/assets/engine-vendor.js:5076:27) at ComputedPropertyPrototype.get (http://localhost:4200/assets/vendor.js:32381:28) at Object.get (http://localhost:4200/assets/vendor.js:37374:19) at RootPropertyReference.compute (http://localhost:4200/assets/vendor.js:30337:26) at RootPropertyReference.value (http://localhost:4200/assets/vendor.js:30204:45)

Hopefully that give you enough info to try to fix it. If you need me to do anything let me know. @dguettler

I encountered this same problem with one of our projects, so think I found where this issue is coming from.

In the _lookupRoute function in the bread-crumbs component, the getOwner(this) function can only look up the routes that exist in the parent application. So, when it encounters a route that is inside of a routable engine, _lookupRoute returns undefined because it can't find the route because the route is owned by the engine, not the parent application that's hosting the engine.

After looking at how Ember Engines modified the internal router service for Ember, I believe that using the routing service and the getHandler(routeName) function will allow the route object to get looked up whether the route belongs to the parent app or an engine. I'm starting to work on a PR now that will hopefully help resolve this.

@dguettler with #143 merged, what are the next steps to publishing a new version to NPM?
