    <p>I'm using ExtJs 4.1.0 and I'm trying to display a grid of data backed by a remote json store. When I render the grid like so:</p> <pre><code>Ext.Loader.setConfig({enabled:true}); Ext.Loader.setPath({ 'Grip':'app' ,'Ext.ux':'ext/examples/ux' }); Ext.require([ 'Grip.view.EditableGrid' ,'Grip.store.UYNMeetingTypes' ,'Grip.view.UYNMeetingGrid' ,'Grip.model.UYNMeeting' ,'Grip.store.UYNMeetings' ,'Ext.ux.CheckColumn' ]); Ext.require([ 'Ext.panel.*', 'Ext.toolbar.*', 'Ext.button.*', 'Ext.container.ButtonGroup', 'Ext.layout.container.Table', 'Ext.tip.QuickTipManager' ]); Ext.onReady(function() { var store = new Grip.store.UYNMeetings(); grid = new Grip.view.UYNMeetingGrid({ store: store ,renderTo: Ext.getBody() }); store.load({ // store loading is asynchronous, use a load listener or callback to handle results callback: function(){ Ext.Msg.show({ title: 'Store Load Callback', msg: 'store was loaded, data available for processing', modal: false, icon: Ext.Msg.INFO, buttons: Ext.Msg.OK }); } }); }); </code></pre> <p>it works fine. However, when I try to link things up using the manner suggested in the MVC tutorial (<a href="http://www.sencha.com/learn/architecting-your-app-in-ext-js-4-part-2/" rel="nofollow">http://www.sencha.com/learn/architecting-your-app-in-ext-js-4-part-2/</a>) I can't seem to get my data to display. I'm running ExtJs 4.1.0 on Google Chrome 20.0.1132.47. Any ideas?</p> <p>I tried to post only the minimally relevant bits of code (though it still seems like a lot). Let me know if there's anything I can clarify. Any help would be greatly appreciated. Thanks!</p> <p>Grip.controller.UYNMeeting:</p> <p>Ext.define('Grip.controller.UYNMeeting', { extend: 'Ext.app.Controller',</p> <pre><code>refs: [{ ref: 'meetingGrid', selector: 'uynmeetinggrid' }], stores: ['UYNMeetings','UYNMeetingTypes'], init: function() { }, onLaunch: function() { var meetingsStore = this.getUYNMeetingsStore(); meetingsStore.load({ callback: this.onMeetingsLoad, scope: this }); var meetingTypesStore = this.getUYNMeetingTypesStore(); meetingTypesStore.load({ callback: this.onMeetingTypesLoad, scope: this }); }, onMeetingsLoad: function() { }, onMeetingTypesLoad: function() { Ext.Msg.show({ title: 'Store Load Callback', msg: 'store was loaded, data available for processing', modal: false, icon: Ext.Msg.INFO, buttons: Ext.Msg.OK }); } </code></pre> <p>});</p> <p>Grip.view.UYNMeetingGrid:</p> <pre><code>var rowEditing = Ext.create('Ext.grid.plugin.RowEditing', { clicksToMoveEditor: 1, autoCancel: false }); Ext.define('Grip.view.UYNComboBox', { extend:'Ext.form.field.ComboBox' ,alias:'widget.uyncombo' ,stores:['UYNMeetingTypes'] }) Ext.define('Grip.view.UYNMeetingGrid', { extend:'Ext.grid.Panel' ,alias:'widget.uynmeetinggrid' ,stores:['UYNMeetings'] ,title:'UYN Meetings Grid' ,hideHeaders: true ,bodyPadding:5 ,width:550 ,height:400 ,autoScroll: true ,initComponent:function(){ this.columns = [{ "width": 150, "text": "Name", "sortable": true, //"id": "name", "dataIndex": "name", editor: { allowBlank: false, xtype: 'textfield' } }, { "width": 150, "text": "Org.", "sortable": true, //"id": "org", "dataIndex": "org", editor: { allowBlank: true, xtype: 'textfield' } }, { "width": 100, "text": "Date", "sortable": true, //"id": "date", "dataIndex": "date", editor: { xtype: 'datefield', allowBlank: false, format: 'm/d/Y', maxText: 'Cannot have a meeting date in the future!', maxValue: Ext.Date.format(new Date(), 'm/d/Y') } }, { "width": 75, "text": "Meeting Type", "sortable": true, //"id": "meeting_type", "dataIndex": "meeting_type"/*, editor: { xtype: 'uyncombo' }*/ }, { "width": 75, "text": "Num Hours", "sortable": true, //"id": "num_hours", "dataIndex": "num_hours", editor: { allowBlank: false, // step: '.1', xtype: 'numberfield' } }]; this.dockedItems = [{ dock:'bottom' ,xtype:'toolbar' ,items: [{ xtype:'button' ,text:'New' ,action:'newuynmeeting' }, { xtype:'button' ,text:'Edit' ,action:'edituynmeeting' }, { xtype:'button' ,text:'Remove' ,action:'removeuynmeeting' }] }]; this.callParent(); } ,plugins: [rowEditing] ,listeners: { 'selectionchange': function(view, records) { // grid.down('#removeEmployee').setDisabled(!records.length); } } }); </code></pre> <p>Grip.view.Viewport:</p> <pre><code>Ext.define('Grip.view.Viewport', { extend: 'Ext.container.Viewport', layout: 'fit', requires: [ 'Grip.view.ContactsPanel' ,'Grip.view.UYNMeetingForm' ,'Grip.view.UYNMeetingGrid' ,'Grip.view.NavBar' ], renderTo: 'app', tbar:{ xtype:'mynavbar' }, items:[{ xtype:'tabpanel', items:[{ title:'Contacts', xtype:'tabpanel', items:[{ title:'Contacts' ,xtype:'contactspanel' },{ title:'Add Contact' ,html:'TODO: Add content' } ] },{ title:'UYN', xtype:'tabpanel', items:[{ title:'UYN Meetings' //,html:'Foo' ,xtype:'uynmeetinggrid' }] }] }] }); </code></pre>

    1. COI don't know if it's a typo, but a grid doesn't have a `stores` config - it can only display the data of one store, thus it has `store` config (singular, not plural)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
