Grails 3.x project doesn't solve spring injection of Grails service classes in controllers, autocomplete doesn't work

As you can see in the screenshot, the spring injection icon is not present. This only affects controllers. In services the injection work as supposed to.

Controllers do not support syntax highlighting, autocomplete of any classes and spring injection. Can you help me with this ? It is very frustrating.

P.S. Also tried to create a new controller. The spring injection works until Idea is closed. Autocomplete works anywhere in the controller class but not in groovy methods or closures.

Tried in latest 2016.2.2 EAP build and 2016.2.1.

Also tried this [IDEA-154252](https://youtrack.jetbrains.com/issue/IDEA-154252) workaround with gradle, nothing works.

Reproduce the problem in a Grails 3.x project using the affected IntelliJ IDEA versions, comparing service classes with controllers and testing a newly created controller. Check whether syntax highlighting, autocomplete, and Spring injection persist after restarting IDEA and work inside methods and closures; done means these controller features work consistently.
