I have the following problem. When I press the Add New Feed button in the feeds.js folder, which should call the onNewFeed function (located in the MainController.js file), an error appears in the console:
Unrecognized alias: widget.feedform
When I add MainController.js in the file requires:['FeedViewer.view.main.FeedForm'] the console displays:
[Ext.Loader] error Some requested files failed to load.

Ext tries to load a component on the fly, looks like feedform is not properly registered.
Have u tried adding
alias: 'widget.feedform',
to your FeedForm.js
Panel.js as comparison:

So i have the following scenario
in my main view i have a container like this:
Ext.define('APP.view.main.Main', {
extend: 'Ext.container.Container',
xtype: 'app-main',
id: 'root',
requires: [
'Ext.menu.*'
],
items:[
'APP.view.main.topBar'
]
});
my APP.view.main.topBar looks like this:
Ext.define('APP.view.main.topBar',{
extend: 'Ext.container.Container',
docked: 'top',
xtype: 'toolbar',
id: 'topBar',
title: 'Meniu',
items:[
{
text: 'Furnizori',
iconCls: 'x-fa fa-qrcode',
menu: 'APP.view.main.menus.menuFurn'

]
});
the problem is i get the following error:
Invalid config, must be a valid config object
i'm trying to include the toolbar in the items of the main
The item in the main class needs to be a proper object. See below:

on click on any button it logging the below
Uncaught TypeError: Cannot read property 'apply' of undefined
what wrong in it???
thanks in advance...
Your methods should not go in the config block. loginButtonTapped, regFormResetButtonTapped and regNewUserButtonTapped. They should come out one level into the class definition, because they are class methods, not configurations.
I have an issue with showing a settings view on the main view when clicking a proper tab. Here is the code for the main view:
Ext.define('App.view.Main', {
extend:'Ext.tab.Panel',
requires: [
'App.view.SettingsView'
],
config: {
fullscreen: true,
tabBarPosition: 'bottom',
items: [
{
title: 'About',
iconCls: 'info',
items: {
docked: 'top',
xtype: 'titlebar',
title: 'Home Screen'
},
html: 'Home Screen'
},
{
title: 'Maps',
iconCls: 'maps',
items:
{
docked: 'top',
xtype: 'titlebar',
title: 'Maps Screen'
},
html: 'Maps Screen'
},
{
title: 'Setiings',
iconCls: 'settings',
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'Settings'
},
{
xtype: 'settingsview',
id: 'settingsview'
}
]
}
]
}
});
And this is the code for the settings view:
Ext.define('App.view.SettingsView', {
extend: 'Ext.form.Panel',
xtype: 'settingsview',
requires: [
'Ext.form.FieldSet',
'Ext.field.Toggle',
'Ext.field.Select',
'Ext.field.Text',
'Ext.Button'
],
config: {
xtype: 'fieldset',
title: 'SettingsView',
instructions: 'In case you do not want the app to detect your location you can enter the city and country.',
items: [
{
name: 'geo',
xtype: 'togglefield',
label: 'Auto detect?',
labelWidth: '55%',
value: '1',
},
{
name: 'units',
xtype: 'selectfield',
label: 'Units',
options: [
{
text: 'Fahrenheit',
value: 'f'
},
{
text: 'Celsius',
value: 'c'
}
]
},
{
name: 'city',
xtype: 'textfield',
label: 'City',
disabled: true
},
{
name: 'country',
xtype: 'textfield',
label: 'Country',
disabled: true
},
{
xtype: 'button',
text: 'Refresh',
action: 'refresh',
margin: '10 5',
ui: 'confirm'
}
]
}
});
When the settings tab is enabled it shows only the title bar and the tab bar. No error messages. What am I doing wrong?
Try to add layout:'fit' in config inside settingsview
OR
Modify your main view
{
title: 'Setiings',
iconCls: 'settings',
layout: 'vbox',
items: [
{
docked: 'top',
xtype: 'titlebar',
title: 'Settings'
},
{
xtype: 'settingsview',
id: 'settingsview',
flex: 1
}
]
}
I have tabpanel, which contains a few tabs. I will be concentrating on the 6th tab here - navigatingPanels.js file. In this file, I have a card layout, so that the user can fill form1 & move to form2 on submission (slide to form2). I also have a docked toolbar, with a back button, so that the user can move back to form1 (if needed). It gives an error -
Uncaught Error: [ERROR][Ext.Base#callParent] Invalid item given: undefined, must be either the config object to factory a new item, or an existing component instance.
The app can be seen here - http://maalguru.in/touch/Raxa-70/MyApp/
Update - If I add one extra card to the concerned panel, & remove the form1 & form2 (required panels/cards), then it works fine. In this case I have to setActiveItem to the desired cards (form1 & form2). Changed Viewport - http://pastebin.com/P4k04dBQ
Is there any solution to achieve with only 2 panels/cards ?
Viewport.js
Ext.define('MyApp.view.Viewport', {
extend: 'Ext.TabPanel',
xtype: 'my-viewport',
config: {
fullscreen: true,
tabBarPosition: 'bottom',
items: [{
xclass: 'MyApp.view.navigatingPanels'
}]
}
});
NavigatingPanels.js
Ext.define('MyApp.view.navigatingPanels', {
extend: 'Ext.Panel',
id: 'navigatingPanels',
xtype: 'navigatingPanels',
config: {
iconCls: 'user',
title: 'Navigating Panels',
layout: 'card',
animation: {
type: 'slide',
direction: 'left'
},
defaults: {
styleHtmlContent: 'true'
},
items: [{
docked: 'top',
xtype: 'toolbar',
title: 'Registeration Form',
items: [{
text: 'Back',
ui: 'back',
align: 'centre',
//back button to take the user back from form2 to form1
handler: function() {
Ext.getCmp('navigatingPanels').setActiveItem(form1);
}
}]
},
form1,
form2
]
}
});
var form1 = new Ext.Panel({
scrollable: 'vertical',
items: [{
xtype: 'fieldset',
title: 'Form 1',
items: [{
xtype: 'textfield',
label: 'Name',
name: 'name',
},
{
xtype: 'button',
text: 'Save Data & move to form2',
ui: 'confirm',
//TODO add some action: to store data
//save data & move to form2
handler: function() {
Ext.getCmp('navigatingPanels').setActiveItem(form2, {
type: 'slide',
direction: 'right'
});
console.log("Form1");
}
}
]
}]
});
var form2 = new Ext.Panel({
scrollable: 'vertical',
items: [{
xtype: 'fieldset',
title: 'Form 2',
items: [{
xtype: 'textareafield',
label: 'Message',

App.js
Ext.Loader.setConfig({
enabled: true
});
Ext.application({
name: 'MyApp',
controllers: ['Main'],
launch: function() {
Ext.create('MyApp.view.Viewport', {
fullscreen: true
});
}
});
Finally I got the answer. The component instances should not be given as items in Ext.define, instead their config should be given. The setActiveItem can be called the the normal way -
Ext.getCmp('navigatingPanels').setActiveItem(0);

Try this...
myNavigationPanel = Ext.create('MyApp.view.navigatingPanels');
myNavigationPanel.setActiveItem(0);
Ext.define('MyApp.view.Viewport', {
extend: 'Ext.TabPanel',
xtype: 'my-viewport',

{
xclass: 'MyApp.view.Products'

},
{
xclass: 'MyApp.view.NestedTabPanels'
},
myNavigationPanel
]
}
});
I'm trying to implement a simple framework for an app. The idea is to create a background viewport type 'layout' with a north region containing the page header and an interchangeable center region.
When my app starts, a Login form is shown. If the user/password is ok, the form is destroyed and the main layout should appear. The main layout should insert a nested layout in its center region.
This is my background layout code:
Ext.define('DEMO.view.BackgroundLayout', {
extend: 'Ext.container.Viewport',
alias: 'widget.background',
requires: [
'DEMO.view.Main'
],
layout: {
type: 'border'
},
initComponent: function() {
var me = this;
Ext.applyIf(me, {
items: [
{
region: 'north',
html: '<h1 class="x-panel-header">Page Title</h1>'
},
{
xtype: 'mainview',
region: 'center',
forceFit: false,
height: 400
}
]
});
me.callParent(arguments);
}
});
The main layout is this:
Ext.define('DEMO.view.Main', {
extend: 'Ext.container.Viewport',
alias: 'widget.mainview',
requires: [
'DEMO.view.MyGridPanel'
],
layout: {
type: 'border'
},
initComponent: function() {
var me = this;
console.log('bb');
Ext.applyIf(me, {
items: [
{
xtype: 'mygridpanel',
region: 'center',
forceFit: false
},
{
xtype: 'container',
height: 38,
forceFit: false,
region: 'north',
items: [
{
xtype: 'button',
height: 34,
id: 'btnLogout',
action: 'logout',
text: 'Logout'
}
]
}
]
});
me.callParent(arguments);
}
});
As you can see, the center region needs an xtype named "mygridpanel". This is the code for it:
Ext.define('DEMO.view.ui.MyGridPanel', {
extend: 'Ext.grid.Panel',
border: '',
height: 106,
title: 'My Grid Panel',
store: 'MyJsonStore',
initComponent: function() {
var me = this;
Ext.applyIf(me, {
viewConfig: {
},
columns: [
{
xtype: 'gridcolumn',
dataIndex: 'Id',
text: 'Id'
},
{
xtype: 'gridcolumn',
dataIndex: 'Name',
text: 'Name'
},
{
xtype: 'gridcolumn',
dataIndex: 'Sales',
text: 'Sales'
}
],
dockedItems: [
{
xtype: 'toolbar',
dock: 'top',
items: [
{
xtype: 'button',
disabled: true,
id: 'btnDelete',
allowDepress: false,
text: 'Delete'
},
{
xtype: 'button',
disabled: true,
id: 'btnEdit',
allowDepress: false,
text: 'Edit'
}
]
}
]
});
me.callParent(arguments);
}
});
My problem is that when I call Ext.create('DEMO.view.BackgroundLayout', {}); it only shows the nested layout, and the background layout is hidden, also I get this error in Chrome's console:
Uncaught Error: HIERARCHY_REQUEST_ERR: DOM Exception 3
What I'm doing wrong?.
Thanks in advance,
Leonardo.
