[play 2.1.4][scala 2.10] I write an simple index.scala.html, I want to set an parameter with default value but fail

I write an simple index.scala.html in view package

@import controllers.Application.AuthenticatedRequest

@(posts: Iterator[Post], message: String = "" )(implicit request: AuthenticatedRequest)
.....

the error is:

[error] F:\Kepler\blog\app\views\posts\index.scala.html:2: ')' expected but '='
found.
[error] @(posts: Iterator[Post], message:String = "")(implicit request: Authenti
catedRequest)
[error]                                         ^

I think it is correct way to set the message default value as "". anyonw know why here is expected ')' instead of '='

As @Max mentioned the first line should contain parameters, and if any parameter type isn't recognized without importing it you should either fully qualify the type name, which in your case should look like:

@(posts: Iterator[Post], message: String = "" )(implicit request: controller.Application.AuthenticatedRequest)

Or if you plan to use the type often in the templates parameters list, then you can specify additional imports in the F:\Kepler\blog\project\Build.scala file, like

val main = play.Project(appName, appVersion, appDependencies).settings(
  ..., // your settings here like resolvers, etc.
  templatesImport += "controllers.Application._",
  templatesImport += "models._", //etc.
  ... // further settings or the end of the list - remember: last item without coma
)

Then the templates are generated with the imports visible to the parameters list.

Play will expect you declare all template parameters at first line. Try this

Try to swap with import line

@(posts: Iterator[Post], message: String = "" )(implicit request: AuthenticatedRequest)

@import controllers.Application.AuthenticatedRequest

The error message is misleading though
