org.apache.camel.model.ThrottleDefinition cannot be cast to org.apache.camel.model.RouteDefinition

Question

I am trying to setup a dynamic route, here https://github.com/vaneyck/testingCamel but it seems that i cant use Java fluent builder syntax to add throttling to the routes if I include routes in other routes.

If I add the throttle code to the routes in grails-app/routes the code works well, but this does not conform to the setup i am using in my code.
