Failed to add new constructs

[MikaelMayer]

Steps to reproduce

I added a new method for API and an object hierarchy similar to TodoPriority (afterwards, I want to use case classes). See the diff here (clone the repository)

https://github.com/MikaelMayer/scalajs-spa-tutorial/commit/71a2ec1ca385d6f7ebe7302b20f59957d77c50cb

Then do sbt run and navigate in your browser to localhost:9000

Expected

No error on the command line

Actual

Request path: spatutorial/shared/Api/getTodos
Request path: spatutorial/shared/Api/getMessage
Request path: spatutorial/shared/Api/motd
Sending 4 Todo items
[error] p.c.s.n.PlayDefaultUpstreamHandler - Cannot invoke the action

Ok I figured out how to correct this.

I had to do sbt clean every time I make modifications to the shared project.

Thanks for this very nice tutorial.
