If the allowed method is POST/GET introduce a variable to redirect to it some action

Instead of showing a 405 allow something like:

static allowedMethods = [[save: "POST",invalidMethodAction="create"], ... ]

which will redirect to some other action which can serve it's purpose which would be equivalent to: (ref: http://www.grails.org/doc/1.3.7/ref/Controllers/allowedMethods.html)

class PersonController {
  def delete = {
    if(request.method == 'GET') {
      // redirect to the list action
      redirect(action:list)
    } else {
      // the rest of the delete action goes here
    }
  }
}

Some gotcha's:

• As given in the above example save and create shouldn't be having the same allowed methods
  • Case 1: save has "POST" and create has "POST". save pushes the get request to create and create shows a 405
  • Case 2: save has suppose invalidMethodAction = create and create has invalidMethodAction = save. You'll experience a stackoverflow.
