Beego找不到控制器

Question

I am working on beego application. I am trying to run the same code in two different machine. Both are ubuntu. In one machine, it runs without any problem but in other I got following error log. I have the same file organization for both, why do you think this might be happening?

controllers/EventController.go:18: this.ServeJson undefined (type *EventController has no field or method ServeJson)
controllers/EventController.go:24: this.ServeJson undefined (type *EventController has no field or method ServeJson)
controllers/EventController.go:30: this.ServeJson undefined (type *EventController has no field or method ServeJson)
controllers/default.go:14: c.TplNames undefined (type *MainController has no field or method TplNames)

Even controller:

package controllers


import (
    "github.com/astaxie/beego"
    "solardatabase/models"
    "solardatabase/dao"
    "solardatabase/services"
)

type EventController struct {
    beego.Controller
}

func (this *EventController) ListEvents() {
    res := struct{ Tasks []*models.Event }{dao.GetAllEvents()}
    this.Data["json"] = res
    this.ServeJson()
}

func (this *EventController) ListEventsByRange() {
    request, _ := models.CreateEventByTimeRangeRequest(this.Ctx.Input)
    this.Data["json"] = dao.EventsByTimeRange(request)
    this.ServeJson()
}

func (this *EventController) TemporalQuery() {
    request, _ := models.CreateTemporalRequest(this.Ctx.Input)
    this.Data["json"] = services.EventsByTimeFilter(request)
    this.ServeJson()
}

I found the problem. Beego released new version between my installation of the machines. I thought it cannot see the whole controller but It was only the name of function.

In new version:

serveJson() -> serveJSON()

Config also changed.

Beego.HttpPort -> beego.BConfig.Listen.HTTPPort
