extjs-mvc

I'm trying to build a very very basic "proof of concept" app using ExtJS but i'm having a very hard time. All i want is two grids getting their data from a remote JSON file, but no matter what i do i keep on getting the error that's in the subject. Here is my simple code: app.js: Ext.Loader.setConfig({enabled:true}); Ext.application({ name: 'GeoSniffer', autoCreateViewport: true, models: ['Location', 'Client'], stores: ['Locations', 'Clients'], }); Viewport.js Ext.define('GeoSniffer.view.Viewport', { extend: 'Ext.container.Viewport', layout: 'fit', requires: [ 'GeoSniffer.view.ClientsList',

I want to learn how can I controller rowEditor plugin inside controller.. Here's rowEditor definition: Ext.define(appName + '.view.department.DepartmentGrid', { initComponent: function() { this.rowEditor = Ext.create('Ext.grid.plugin.RowEditing', { clicksToEdit: 2 }); } } ** Controller** this.control({ 'departmentgrid': { // ?? } }); It's in the docs: http://docs.sencha.com/ext-js/4-1/#!/api/Ext.grid.plugin.RowEditing-event-edit this.control({ 'departmentgrid': { edit: this.onDepartmentGridEdit } }); 来源： https://stackoverflow.com/questions/11914525/ext-js-4-how-to-control-roweditor-inside

I need to override Ext.data.Connection to show a Login Form. I do this at the moment in Ext.application.launch which works as expected. Is it possible to swap this piece of code somewhere different like in an extra file? If you need this only to recognize when user is not authenticated you might want to consider doing something else. Like adding a handler to Ajax singleton: function addAjaxErrorHandler(object) { Ext.Ajax.on('requestexception', function(conn, response, options, e) { var statusCode = response.status, errorText = null, captionText = response.statusText; // 404 - file or method
