  • What are you trying to do?
    I want create a custom response for controller as describe in the documentation. (https://revel.github.io/manual/results.html#CustomResult).

  • What would you expect to happen?
    I want render a simple text.

    The first time the request (http://localhost:9000) is executed works successfully, but when reload page this returns 502 error.

My App controller:

package controllers

import (
	"net/http"

	"github.com/revel/revel"
)

type MyHtml string

type App struct {
	*revel.Controller
}

func (c *App) Index() revel.Result {
	return MyHtml("<html><body>Hello Result</body></html>")
}

func (r MyHtml) Apply(req *revel.Request, resp *revel.Response) {
	resp.WriteHeader(http.StatusOK, "text/html")
	resp.Out.Write([]byte(r))
}

Or include a screenshot / video of the issue.

You're using Atom, using something completely unrelated to this plugin, and posting a request for help... on the wrong project... ?
