First off: There are a bunch of questions about this exact thing all over the place. I have spent the better part of a day reading through them all and clearly I am still failing to understand this.
I am getting my store data from a httprequest (rather than standard ajax call) and this is working and adding my data to the store. But whatever I try, this data will not populate the list. Currently my code looks like:
Model:
Ext.define('estarCamera.model.Event', {
extend: 'Ext.data.Model',
config: {
fields: [
'Id',
'Title',
'Content',
'Image',
'Location',
'Latitude',
'Longitude',
'Radius',
'Starts',
'Expires',
'Prestart'
]
}
});
Store:
Ext.define('estarCamera.store.Events', {
extend: 'Ext.data.Store',
config: {
model: 'estarCamera.model.Event',
storeId: 'EventStore'
}
});
Data is populating the store:
var jsonResponse = JSON.parse(xhr.responseText);
if(jsonResponse.status == "Success"){
//Success
var eventsJsn = JSON.parse(jsonResponse.message);
$.each(eventsJsn, function(){
$.each(this, function(k,v){
//Events root element
$.each(this, function(k,v){
//Each 'Event' element
var eStore = Ext.getStore('EventStore');
eStore.add({
Id: this.ID,
Title: decodeURIComponent(this.Title),
Content: decodeURIComponent(this.Content),
Image: this.Image,
Location: this.Location,
Latitude: this.Latitude,
Longitude: this.Longitude,
Radius: this.Radius,
Starts: this.Starts,
Expires: this.Expires,
Prestart: this.Prestart
});
eStore.sync();
})
});
});
Ideally this will then populate:
Ext.define('estarCamera.view.Events', {
extend: 'Ext.Panel',
xtype: 'events',
requires: [
'estarCamera.store.Events',
'Ext.form.FieldSet',
'Ext.List'
],
config: {
title:'Events',
iconCls: 'star',
layout: 'vbox',
items:[
{
docked: 'top',
xtype: 'toolbar',
title: 'Active Events'
},
{
xtype: 'container',
layout: 'fit',
flex: 10,
items:[{
xtype:'list',
title: 'Events',
width: '100%',
height: '100%',
store: 'Events',
styleHtmlContent: true,
itemTpl: new Ext.XTemplate(
'<div class="outerEvent">',
'<h1>title{Title}</h1>',
'<p>{Content}</p>',
'</div>'
)
}]
}]
}
});
Does anyone know why this is happening?
OK, feeling a bit fooling now .. eventually (after an embarrassingly long time) found that this was because my list was trying to reference 'Events' which is the name of my store and how I thought it was supposed to work. Changed this to 'EventStore' (the storeid of my store) and it worked perfectly.

I have a fully functional Sencha Touc 2.1.1 app bundled in Phonegap 2.5. In it, I have several lists that I use to spawn form panels for data entry and other sundry activities.
An example one is as follows (it happens on all my form panels that get opened via a list tap):
I have a list with an item template is rendered in this container:
Ext.define('EvaluateIt.view.Push', {
extend: 'Ext.Container',
fullscreen: true,
//requires: ['Ext.TitleBar'],
alias: 'widget.pushview',
config: {
layout: 'vbox',
layout: 'fit',
//id: 'pushview',
items: [
{
xtype: 'toolbar',
docked: 'top',
items: [
{
xtype: 'button',
itemId: 'loginButton',
text: 'Login',
iconCls: 'arrow_right',
iconMask: true
},
{
xtype: 'button',
itemId: 'logOutButton',
text: 'Logout',
iconCls: 'arrow_right',
iconMask: true
}
]
},
{
flex: 1,
xtype: 'pushList'
}
],
listeners: [{
delegate: '#logOutButton',
event: 'tap',
fn: 'onLogOutButtonTap'
}]
},
onLogOutButtonTap: function () {
this.fireEvent('onSignOffCommand');
}
});
The list is:
Ext.define('EvaluateIt.view.PushList', {
extend: 'Ext.dataview.List', //'Ext.tab.Panel',
alias : 'widget.pushList',
config: {
width: Ext.os.deviceType == 'Phone' ? null : 300,
height: Ext.os.deviceType == 'Phone' ? null : 500,
xtype: 'list',
store: 'SiteEvaluations', //getRange(0, 9),
itemTpl: [
'<div><strong>Address: {address}</strong></div> '
],
variableHeights: false
}
});
And the form that is opened on tapping an address rendered in the itemTpl is:
Ext.define('EvaluateIt.view.PushForm', {
extend: 'Ext.form.Panel',
alias : 'widget.pushForm',
requires: [
'Ext.form.Panel',
'Ext.form.FieldSet',
'Ext.field.Number',
'Ext.field.DatePicker',
'Ext.field.Select',
'Ext.field.Hidden'
],
config: {
// We give it a left and top property to make it floating by default
left: 0,
top: 0,
// Make it modal so you can click the mask to hide the overlay
modal: true,
hideOnMaskTap: true,
// Set the width and height of the panel
//width: 400,
//height: 330,
width: Ext.os.deviceType == 'Phone' ? screen.width : 350,
height: Ext.os.deviceType == 'Phone' ? screen.height : 500,
scrollable: true,
layout: {
type: 'vbox'
},
defaults: {
margin: '0 0 5 0',
labelWidth: '40%',
labelWrap: true
},
items: [
{
xtype: 'textfield',
name: 'address',
readOnly: true
},
/*{
xtype: 'checkboxfield',
id: 'addImage',
label: 'Upload Image'
},*/
{
xtype: 'button',
itemId: 'save',
text: 'Push to server'
}
]
}
});
This is called as a ViewPort via the following method in my controller:
onSelectPush: function(view, index, target, record, event) {
console.log('Selected a SiteEvaluation from the list');
var pushForm = Ext.Viewport.down('pushForm');
if(!pushForm){
pushForm = Ext.widget('pushForm');
}
pushForm.setRecord(record);
pushForm.showBy(target);
console.log('Selected a Push from the list ' + index + ' ' + record.data.address);
}
This usually works as expected:
Open Push view
Tap on address in list
PushForm opens for user to do their thang.
However! Occasionally, when the user taps on the address, instead of the PushForm opening a black arrow shows up underneath the address in the list (see attached image)
.
It is unpredictable when this will happen, but it does. So far, its only happened on my Android device, not on an emulator or in a Web browser (I have not yet heard from any of my iOS users about this yet).
Note: The only way to get the app to function "normally" again is to either do a complete restart or a force close of the application.
Any ideas what is causing it? Grazie!!
I am using the following Xtemplate to filter out items by category (see view/panel in which it is "housed" below):
itemTpl: new Ext.XTemplate(
'<tpl for=".">',
'<tpl if="category === \'vegetable\'">',
'{str}',
'</tpl>',
'</tpl>'),
and it is filtering as expected (well, at least partially).
I have the following store:
Ext.define("Produce.store.List", {
extend: 'Ext.data.Store',
alias: 'store.List',
config: {
model: 'Produce.model.Food',
sorters: 'category',
grouper: function(record) {
return record.get('category')[0];
},
data: [
{ category: 'fruit', str: 'tomato'},
{ category: 'fruit', str: 'green bean'},
{ category: 'vegetable', str: 'celery'},
{ category: 'vegetable', str: 'sprouts'},
{ category: 'fruit', str: 'squash'},
{ category: 'fruit', str: 'snap peas'},
{ category: 'vegetable', str: 'rhubarb'},
{ category: 'vegetable', str: 'cabbage'}
]
}
});
The Xtemplate is rendered in the following view/panel:
Ext.define('Produce.view.Vegetable', {
extend: 'Ext.tab.Panel',
requires: ['Produce.model.Food'],
config: {
tabBar: {
docked: 'top',
ui: 'neutral',
layout: {
pack: 'center'
}
},
items: [{
title: 'Produce',
layout: Ext.os.deviceType == 'Phone' ? 'fit' : {
type: 'vbox',
align: 'center',
pack: 'center'
},
cls: 'demo-list',
items: [{
width: Ext.os.deviceType == 'Phone' ? null : 300,
height: Ext.os.deviceType == 'Phone' ? null : 500,
xtype: 'list',
store: 'List',
itemTpl: new Ext.XTemplate(
'<tpl for=".">',
'<tpl if="category === \'vegetable\'">',
'{str}',
'</tpl>',
'</tpl>'),
variableHeights: false
}]
}
});
When I run this only the vegetables in the store are displayed in the panel- which is great - but blank rows are also displayed where the fruit items were filtered out in the rendered list - which is not great. (Similarly, in my "fruit" view, fruit are displayed as desired, but where there were vegetables, blanks rows show up).
How can I get rid of these blank rows (this is an issue, since the fruits and vegetables in my list are just to get the app working, and are a fill-in to represent a much larger number of records that will be categorized for my actual app). I tried using Ext.IsEmpty and filtering by null, but neither of these did the trick.
The View is working well: it shows a row for each record. You should try to add a filtered store to the list.
Take a look at Ext.util.Filter in the Sencha Touch documentation.
This will solve your problem!
I would dynamically change the title of my list titlebar. This is my app.js where you can view my app (see var list where there is the toolbar item and title that I would change)
How can I do this?
Thanks.

Ext.List component's superclass is Ext.DataView., not Ext.Panel.
Hence, it is not possible to directly add / dock any item inside the Ext.List component.
So, I recommend you to wrap your Ext.List component inside Ext.Panel.
Do it like this,
var myStore = Ext.create('Ext.data.Store', {
storeId: 'MyStore',
fields: ['txt']
}); // create()
var listpanel = new Ext.Panel({
layout: 'fit', // important to make layout as 'fit'
items: [
{
xtype: 'titlebar',
id: 'myTitle',
docked: 'top',
title: 'Before Change title',
items: [
{
xtype:'button',
text:'Change Title',
align:'right',
listeners : {
tap : function() {
Ext.getCmp('myTitle').setTitle('After Title Change');
}
}
}
]
},
{
//Definition of the list
xtype: 'list',
itemTpl: '{txt}',
store: myStore,
}]
});
....
....
{
title: '2-tab',
layout:'fit',
items: [listpanel],
cls: 'card2'
},
....
....
Sample Output :-
Before changing the title
After changing the title
FYI, If you look inside the Ext.List class in Sencha Docs, you will see the following code inside initComponent() method,
if (Ext.isDefined(this.dockedItems)) {
console.warn("List: List is not a Panel anymore so you can't dock items to it. Please put this list inside a Panel with layout 'fit'");
}
I cannot figure out how I can retrieve a given Data item in a store (id-number) to send it to the "setActiveItem" method in a listener:
So I have a store - model:
Ext.regModel('PictureItem', {
fields: ['id', 'titel', 'url']
});
var pictureItems = new Ext.data.Store({
model: 'PictureItem',
data: [
{id:1, titel:'page 1', url:'http://placekitten.com/1024/768'},
{id:2, titel:'page 2', url:'http://placekitten.com/1024/768'},
{id:3, titel:'page 3', url:'http://placekitten.com/1024/768'},
]
});
Here is my menuList called "leftList":
var leftList = new Ext.List({
dock: 'left',
id:'list1',
width: 135,
overlay: true,
itemTpl: '{titel}',
singleSelect: true,
defaults: {
cls: 'pic'
},
store: pictureItems,
listeners:{
selectionchange: function (model, records) {
if (records[0]) {
Ext.getCmp('karte').setActiveItem(!!!Here the number of the selected Item
or respondend "id" in the data store!!!);
}
}
}
});
and the carousel....
var carousel = new Ext.Carousel({
id: 'karte',
defaults: {
cls: 'card'
},
items: [{
scroll: 'vertical',
title: 'Tab 1',
html: '<img class="orientation" alt="" src="img_winkel/titel_v.jpg">'
},
If I call
Ext.getCmp('karte').setActiveItem(2);
it works with the called card - but how can I get the number from the id of the selected item in the menu List /store????
By the way: what does mean:
if (records[0]) {
why [0]?
I FOUND THE ANSWER FOR MYSELF - IT'S EASY:
Ext.getCmp('karte').setActiveItem(records[0].get('id'), {type: 'slide', direction: 'left'});
The secret to get the record-entry is ".get()":
records[0].get('arrayfield')
So now I can change the activeItem in the carousel easely...
I'm building an app and i've got a list loaded with some info from store, it has a lot of items in it but when I try to scroll down it scrolls back up as if there were not enough items to scroll. Here is some code:
app.views.SearchTab = Ext.extend(Ext.Panel, {
iconCls: 'search',
id: 'search',
items: {
xtype: 'list',
store: app.stores.results,
scroll: 'vertical',
itemTpl: '<div class="list_left_panel"><div class="list_photo_wrapper"><div class="list_photo"><img src="http://realio.cz/images/{link}_0s.jpg" /></div></div></div><div class="list_right_panel"><div class="list_name">{titul}</div><div class="list_info"><div>{cena} Kč</div><div class="list_info_grey">{m2} m<sup>2</sup></div><div>{typ}</div></div></div>',
onItemDisclosure: function (record) {
Ext.dispatch({
controller: app.controllers.detail,
action: 'show',
id: record.getId()
});
}
},
initComponent: function() {
app.stores.results.load();
app.views.SearchTab.superclass.initComponent.apply(this, arguments);
}
});
app.models.Results = Ext.regModel("app.models.Results", {
fields: [
{name: "titul", type: "string"},
{name: "book_id", type: "int"},
...
{name: "u", type: "int"}
]
});
app.stores.results = new Ext.data.Store({
model: "app.models.Results",
proxy: {
type: 'ajax',
url: 'http://site.com/json_list2.php?...',
reader: {
type: 'json',
root: 'markers'
}
},
autoLoad: false
});
How can i fix the list so that it scrolls correctly? Thanks.
