Help needed and Netzke Guru wanted

[Ivan Parovozoff]

Probably i'm very stupid, but i can't understand how to create component for my app like bosses_and_clerks from Demo. 

Code from demo modified for my models - ends with JS error in callback -

 view = this.getComponent('comp_name').getView();

ERR_MSG: 

Uncaught TypeError: Cannot call method 'getView' of undefined

Ruby 2.1.0 - Rails 4.0.3 - ExtJS 4.2.2 

Tutorial from  Github too old and can't help

What i do wrong? 

class Application < Netzke::Basepack::Viewport

  include Netzke::Basepack::ItemPersistence

  def configure(c)

    super

    c.items = [

        layout: :border,

        border: true,

        id: :main_frame,

        items: [

                { region: :west, width: 200, split: true, layout: :fit, items: [

                    { region: :center, component: :countries }

                ]},

                { region: :center, split: true,  layout: :fit, items: [

                    {region: :center, component: :provinces }

                ]},

                { region: :east, split: true, width: 400, layout: :fit, items: [

                    {region: :center, component: :cities }

                ]}

              ]

               ]

  end

  js_configure do |c|

    c.layout = :fit

    c.padding = 2

      # Overriding initComponent

      c.init_component = <<-JS

      function(){

        // calling superclass's initComponent

        this.callParent();

        // setting the 'rowclick' event

        var view = this.getComponent('provinces').getView();

        view.on('itemclick', function(view, record){

          // The beauty of using Ext.Direct: calling 3 endpoints in a row, which results in a single call to the server!

          this.selectProvince({provicne_id: record.get('id')});

          this.getComponent('cities').getStore().load();

        }, this);

      }

      JS

  end

  component :provinces do |c|

    c.klass = Provinces

    #include PgGridTweaks

  end

  component :countries do | c |

    c.klass = Countries

    c.model = 'Country'

    #include PgGridTweaks

  end

  component :cities do |c|

    c.klass = Cities

    c.model = "City"

    #include PgGridTweaks

    c.data_store = {auto_load: true}

    c.scope = {:province_id => component_session[:selected_province_id]}

    c.strong_default_attrs = {:province_id => component_session[:selected_province_id]}

  end

  # region selected

  endpoint :select_province do | params, this |

    component_session[:selected_province_id] = params[:province_id]

  end

 Увы, английский плох, много хуже чме когда начинал его изучать, но в русской ветке вообще тищина ;)

Self answered question :)

I'm GURU??? No, i'm noob ... 

Solution was finally found. That's god. Chain of linked models required more accuracy.
