Async-feature in grails 2.0.0.M1

i am trying out the async-feature in grails. According to http://grails.org/doc/2.0.0.M1/guide/introduction.html#webFeatures it is now possible to use the servlet 3.0 async-feature in grails. So i tried the following code (copied from the doc):

def index() {
    def ctx = startAsync()
    ctx.start {
        render "hello"
        ctx.complete()
    }
}

just to see if it works, sadly it does not work :/. A groovy.lang.MissingMethodException is thrown. Message: No signature of method: grailsasync.ProductController.startAsync() is applicable for argument types: () values: []. While compiling i get no errors, only whi开发者_如何学Gole executing.

So i ask myself what did i do wrong? Maybe someone has tried out the new Milestone of grails and can help me with that.

Your code looks fine. Assuming you've already confirmed that you're running this on a container that supports v 3.0 of the Servlet specification, I'd create an issue about this in the Grails JIRA
