How to add task in taskbar

Without any code it’s hard to guess. Maybe the meta data is wrong or App.TaskManager.touch(@taskKey) is missing?

Here is a simple example of the profile page:

http://127.0.0.1:3000/#example/profile/2
http://127.0.0.1:3000/#example/profile/3
http://127.0.0.1:3000/#example/profile/4

app/assets/javascripts/app/controllers/example_profile.coffee

class App.ExampleProfile extends App.Controller
  @requiredPermission: ['ticket.agent']

  constructor: (params) ->
    super

    @render()

  meta: =>
    meta =
      url: @url()
      id:  @user_id
      head: "example #{@user_id}"
      title: "example #{@user_id}"
      active: true
      iconClass: 'user'
    meta

  url: =>
    '#example/profile/' + @user_id

  show: =>
    @navupdate(url: '#', type: 'menu')

  render: (user) =>
    @html "test #{@user_id}"

class Router extends App.ControllerPermanent
  @requiredPermission: ['ticket.agent']

  constructor: (params) ->
    super

    # check authentication
    @authenticateCheckRedirect()

    # cleanup params
    clean_params =
      user_id:  params.user_id

    App.TaskManager.execute(
      key:        "Example-#{@user_id}"
      controller: 'ExampleProfile'
      params:     clean_params
      show:       true
    )

App.Config.set('example/profile/:user_id', Router, 'Routes')
