Error while accessing List[String] in play framework

I am trying to access List[String] in controller so I write the code: My View is

@(path:List[String])
   ...
    <button type=submit id=imgButton><a href="@routes.Application.confirmDelete(path)">Delete</a></button>

My routes is

   GET     /confirmDelete/:path      controllers.Application.confirmDelete(path:List[String])

My controller is:

def confirmDelete(path:List[String])=Action{
     Ok("deleted "+path);
     }

But it gives me error as

   No URL path binder found for type List[String]. Try to implement an implicit PathBindable for this type.

The error here is absolute clear. Play does not have any idea how to serialize List[String] to and from uri. You can implement implicit PathBindable conversion for List[String] or submit this list as coma separated String and build List[String] on controllers side from String parameter.

Documentation about PathBindable - http://www.playframework.com/documentation/api/2.1.x/scala/index.html#play.api.mvc.PathBindable

Also you may check here for second solution - Play framework 2: Use Array[String] in route
