Controller , Required by Directive

Question

I get the error "Controller 'gssResponseGroup', required by directive 'ngClass', can't be found!" when using the linked Plunker files. Problem is, sometimes it works perfectly fine and other times I get this error. My guess is that the order of loading/compiling of the directives is not consistent.

Anyone have any ideas?

Plunker

I don't see why it states that it can't be found. It is defined right above in the same JavaScript file.

I can't recreate your error, but I am guessing the imperative transclude() call in your link function is creating a race condition. You're using pre-1.2 transcludes with 1.3, so take a look at the current docs for your transcluding needs: https://docs.angularjs.org/guide/directive

I'm also pretty sure the error is not referring to a dependency injection lookup failure, but because the require: '^gssResponseGroup', line in your sub-directive can't find the not-yet-instantiated / linked controller of a parent directive, since it's being transcluded in an ad-hoc way.
