I am looking at a Play Framework 2 view that starts with the following declarations:
@()
@main("Product Form")
I understand the call @main("Product Form") is passing a String object to the main template. What's with the @() call though? Is it required to declare that if the template is not receiving any arguments from its caller?
In first line you need to declare parameters of the view (which is a Scala function as you know from the doc) however if view doesn't get any params most probably you can remove the @() line without any problem.
