play-salat doesn't work with activator-1.2.8 (play 2.2, scala 2.11)

We're using activator-1.2.8, which includes play 2.3.2 and scala 2.11

When I added play-salat, I get the following exception upon the first call that uses Mongo:

Caused by: play.api.PlayException: SalatPlugin is not registered.[You need to register the plugin with "500:se.radley.plugin.salat.SalatPlugin" in conf/play.plugins]
    at se.radley.plugin.salat.package$$anonfun$mongoCollection$2.apply(package.scala:17) ~[play-plugins-salat_2.11-1.5.0.jar:1.5.0]

    at models.Application$.collection(Application.scala:27) ~[classes/:na]

However, I already have a conf/play.plugins with that line in it.

How do I get this to work?

Ah, I was missing the following line:

mongodb.default.db = "mongo"

Can you maybe change the error message, so that it is more specific? Right now, it's misleading.

@txntxn I'll have a look :)
