Play configuration Injectornot working for me

[aberfeldy]

Hey, maybe I'm missing something essentially, but I can't get scaldi to work with application.conf in play. the only thing which happens is

Caused by: scaldi.InjectException: No binding found with following identifiers:
  * TypeTagIdentifier(String)
  * StringIdentifier(riak.uri)

my application.conf:

riak.uri="localhost"
riak.uri=${?RIAK_URI}
riak.port=18098
riak.port=${?RIAK_PORT}

play.application.loader = scaldi.play.ScaldiApplicationLoader
play.modules.enabled += "modules.ApplicationModule"

and in side my ApplicationModule I try to bind them to my beautiful riakclient:

  bind[RiakClient] to RiakClient(
    system,
    inject[String](identified by "riak.uri"),
    inject[Int](identified by "riak.port")
  )

Which compiles beautifully, but when running it, it throws the exception above. Since it (almost) looks like the example and I tried to follow the docs as close as possible, I'm really not sure, what happens there or why it doesn't look into the conf for retrieving the values.

play-version is 2.5.3 scaldi-play is 0.5.15

Greetings
