Extjs issue with PagingToolbar - same data on the next page

There are so many issues I found about different problems with grid paging but still can't find the answer to mine.
I want to load some data from googleapis to extjs grid with ability of paging.
Let say we can query Google JSON API using the following link.
https://www.googleapis.com/books/v1/volumes?fields=totalItems,items(id,volumeInfo/title,volumeInfo/subtitle,volumeInfo/authors,volumeInfo/publishedDate,volumeInfo/description,volumeInfo/imageLinks)&q=Neuromarketing&maxResults=40&startIndex=0
As you can see, I can query as much records per time as 'maxResults' and from the 'startIndex' position.
The short example of json is
{
"totalItems": 298,
"items": [
{
..
First, I've defined a Model and a Store:
Ext.define('MyApp.view.main.Book', {
extend: 'Ext.data.Model',
fields: [
{name: 'id'},
{name: 'publishedDate', mapping: 'volumeInfo.publishedDate'},
{name: 'title', mapping: 'volumeInfo.title'}
]
});
Ext.define('MyApp.view.main.Books', {
extend: 'Ext.data.Store',
model: 'MyApp.view.main.Book',
buffered: true,
pageSize: 15,
alias: 'store.books',
autoLoad: true,
proxy: {
type: 'jsonp',
url: 'https://www.googleapis.com/books/v1/volumes?fields=totalItems,items(id,volumeInfo/title,volumeInfo/subtitle,volumeInfo/authors,volumeInfo/publishedDate,volumeInfo/description,volumeInfo/imageLinks)',
extraParams: {
q : 'Javascript',
maxResults : 15,
startIndex : 0
},
reader: {
type: 'json',
rootProperty: 'items',
totalProperty: 'totalItems'
}
}
});
Second, I've defined a View
Ext.define('MyApp.view.main.Main', {
extend: 'Ext.container.Container',
requires: [
'MyApp.view.main.MainModel'
],
xtype: 'app-main',
controller: 'main',
viewModel: {
type: 'main'
},
layout: {
type: 'border'
},
items: [
{
region: 'center',
xtype: 'tabpanel',
reference: 'tabPanel',
items:[
{
title: 'Result',
reference: 'tabPanelResultTab',
layout: 'fit',
items: [{
xtype: 'grid',
reference: 'grid',
title: 'Books',
dockedItems: [{
xtype: 'pagingtoolbar',
bind: {
store: '{summary}'
},
dock: 'bottom',
displayInfo: true
}],
bind: {
store: '{summary}'
},
columns: [
{ text: 'Google ID', dataIndex: 'id', flex: 1 },
{ text: 'Title', dataIndex: 'title', flex: 4 },
{ text: 'Published Date', dataIndex: 'publishedDate', flex: 1}
]
}]
}]
}]
});
Third, I've defined ViewModel
Ext.define('MyApp.view.main.MainModel', {
extend: 'Ext.app.ViewModel',
requires: [
'MyApp.view.main.Books'
],
alias: 'viewmodel.main',
data: {
name: 'MyApp'
},
stores: {
summary: {
type: 'books'
}
}
});
So now, when I click next page on pagingtoolbar, the loading image pops up, then loads exact the same data on the 2nd page I saw on the 1st page. I still don't understand, how to tell PagingToolbar to query from next 'startIndex'. Is it possible to change 'start' and 'limit' variables to my 'startIndex' and maxResults'?

Yes, you can configure it at the proxy level. See startParam and limitParam.

Extjs GridFilter feature don't work

I'm working in a Ruby On Rails + Ext js app.. and I'm trying to show a grid with the filter feature but I can't I've been reading a lot of post and even the Sencha example page but I can't make it work.
Here is the live code.. a simple grid without the gridpanel working https://fiddle.sencha.com/#fiddle/3fh
Ext.Loader.setConfig({enabled: true});
Ext.Loader.setPath('Ext.ux', '../ux');
Ext.require([
'Ext.grid.*',
'Ext.data.*',
'Ext.ux.grid.FiltersFeature',
'Ext.toolbar.Paging'
]);
var store = Ext.create('Ext.data.Store', {
fields: [
{name: 'tipo', type: 'string'},
{name: 'concepto', type: 'string'},
{name: 'ingreso', type: 'int'},
{name: 'egreso', type: 'int'},
{name: 'por_alicuota', type: 'float'},
{name: 'fecha', type: 'string', dateFormat:'m/Y'}
] ,
data: [
{tipo:'Fijo',concepto:'Ingresos por Cuotas',ingreso:345000,egreso:0,por_alicuota:0,fecha:'11/2013'},
{tipo:'Extra',concepto:'Ingresos por Sanciones',ingreso:24500,egreso:0,por_alicuota:0,fecha:'11/2013'}
],
})
var filtersCfg = {
ftype: 'filters',
local: true,
filters: [{
type: 'string',
dataIndex: 'tipo'
}, {
type: 'string',
dataIndex: 'concepto'
}]
};
var grid = Ext.create('Ext.grid.Panel', {
renderTo: Ext.getElementById("leftPanel"),
store: store,
height: 300,
filters : [filtersCfg],
title: "grid view",
columns: [
{
text: 'Pay',
sortable: true,
filterable: true,
dataIndex: 'tipo'
},
{
text: 'Concept',
sortable: true,
filterable: true,
dataIndex: 'concepto',
}]
});
Ext.onReady(function() {
Ext.QuickTips.init();
grid.render('content');
grid.show();
});
Hope you guys can help me!

Replace filters: [filtersCfg], with features: [filtersCfg],, and remove this extra comma in dataIndex: 'concepto', which is likely to crash IE. It's important to note that the ExtJS file loader seems not to work in this fiddle (Type Error).

Thanks to #Wared for the Answer... The only thing to change in the original code is :
filters: [filtersCfg]
INTO features: [filtersCfg] now the code looks like:
Ext.Loader.setConfig({enabled: true});
Ext.Loader.setPath('Ext.ux', '../ux');
Ext.require([
'Ext.grid.*',
'Ext.data.*',
'Ext.ux.grid.FiltersFeature',
'Ext.toolbar.Paging'
]);
var store = Ext.create('Ext.data.Store', {
fields: [
{name: 'tipo', type: 'string'},
{name: 'concepto', type: 'string'},
{name: 'ingreso', type: 'int'},
{name: 'egreso', type: 'int'},
{name: 'por_alicuota', type: 'float'},
{name: 'fecha', type: 'string', dateFormat:'m/Y'}
] ,
data: [
{tipo:'Fijo',concepto:'Ingresos por Cuotas',ingreso:345000,egreso:0,por_alicuota:0,fecha:'11/2013'},
{tipo:'Extra',concepto:'Ingresos por Sanciones',ingreso:24500,egreso:0,por_alicuota:0,fecha:'11/2013'}
],
})
var filtersCfg = {
ftype: 'filters',
local: true,
filters: [{
type: 'string',
dataIndex: 'tipo'
}, {
type: 'string',
dataIndex: 'concepto'
}]
};
var grid = Ext.create('Ext.grid.Panel', {
renderTo: Ext.getElementById("leftPanel"),
store: store,
height: 300,
features : [filtersCfg],
title: "grid view",
columns: [
{
text: 'Pay',
sortable: true,
filterable: true,
dataIndex: 'tipo'
},
{
text: 'Concept',
sortable: true,
filterable: true,
dataIndex: 'concepto',
}]
});
Ext.onReady(function() {
Ext.QuickTips.init();
grid.render('content');
grid.show();
});

grid loadmask won't disappear while using PagingMemoryProxy

I am trying to create a grid with store having PagingMemoryProxy.
Pagination is working and I can see as well as change all pages
but the loadmask won't disappear so I am not able to edit the grid data.
here is my code
Ext.require('Ext.ux.data.PagingMemoryProxy');
var data = {
Accounts: [{
id: 1,
name: 'Ed Spencer'
}, {
id: 2,
name: 'Abe Elias'
}, {
id: 3,
name: 'Tom Elias'
}]
};
Ext.define('Account', {
extend: 'Ext.data.Model',
fields: [{
name: 'id',
type: 'string'
}, {
name: 'name',
type: 'string'
}]
});
var store = Ext.create('Ext.data.Store', {
storeId: 'myStore',
pageSize: 2,
model: 'Account',
data : data,
proxy: {
type: 'pagingmemory',
reader: {
type: 'json',
root: 'Accounts'
}
},
});
var pagingBar = new Ext.PagingToolbar({
store: store,
displayInfo: true,
displayMsg: 'Displaying Accounts {0} - {1} of {2}',
emptyMsg: "No Accounts to display"
});
var grid = new Ext.create('Ext.grid.Panel', {
title: 'Accounts',
store: store,
columns: [{
header: 'Id',
dataIndex: 'id',
editor: 'textfield'
}, {
header: 'Name',
dataIndex: 'name',
flex: 1,
editor: {
xtype: 'textfield',
allowBlank: false
}
}],
plugins: [
Ext.create('Ext.grid.plugin.RowEditing', {
clicksToEdit: 1,
pluginId: 'rowEditing'
})],
height: 200,
width: 400,
loadMask: false,
renderTo: "editor-grid",
bbar: pagingBar
});
Store load event is getting fired and I can see greyed out data behind the loading mask
Firbug is showing no error.
I am using Extjs 4.1.3. Any idea what's the problem.
Thanks in advance

Looks like a known bug, think its fixed in Extjs 4.2.1
As a temporary fix, you can hide the mask 'on store load' using
grid.getView().setLoading(false);

How can I get the id in Extjs checkcolumn?

Im tiro in Extjs.
That is my model:
Ext.define('CatModel', {
extend: 'Ext.data.Model',
idProperty: 'id',
fields: [{
name: "name",
convert: undefined
}, {
name: "id",
convert: undefined
}]
});
store:
var store = Ext.create('Ext.data.TreeStore', {
model:'CatModel',
root: {
expanded: true
},
proxy: {
type: 'ajax',
reader: 'json',
url: 'item_access.jsp?fullpage=true&show_cat=1'
}
});
and treePanel:
var treePanel = Ext.create('Ext.tree.Panel', {
id: 'tree-panel',
title: 'Sample Layouts',
region:'north',
split: true,
height: 560,
minSize: 150,
rootVisible: false,
autoScroll: true,
store: store,
columns: [
{
xtype: 'treecolumn',
text: 'name',
flex: 2.5,
sortable: true,
dataIndex: 'name'
},
{
text: 'id',//I want to get this id
flex: 1,
dataIndex: 'id',
sortable: true
}
, {
xtype: 'checkcolumn',
text: 'Done',
dataIndex: 'done',
width: 55,
stopSelection: false,
menuDisabled: true,
listeners:{
checkchange:function(cc,ix,isChecked){
//alert(isChecked);
//I want to get this row id in here
}
}
}]
});
In checkchange function there are three parameter one unknown,two is index, and three is check status ...
So how can I get the the same row id where I check the checkbox??
Can I find that id number by checkbox row index??

You should be able to get the record from the TreeView with the row index, and then get the id property from it:
listeners:{
checkchange: function(col, idx, isChecked) {
var view = treePanel.getView(),
record = view.getRecord(view.getNode(idx));
console.log(record.get('id'));
}
}

ExtJs 4 Grid Paging

I'm trying to make data grid with paging using ExtJs framework, but unfortunately my code doesn't work. Maybe some of you has already settled this such problem.
Json-reply from server is:
{
"totalCount":"2",
"companies":[
{
"id":"1",
"name":"Name1",
"region":"Reg1",
"address":"Addr1",
"dealCount":"3",
"dealAmount":"19250",
"latestDealDate":"2012-01-09"
},
{
"id":"2",
"name":"Name2",
"region":"Reg2",
"address":"Addr2",
"dealCount":"2",
"dealAmount":"12150",
"latestDealDate":"2012-01-08"
}
]
}
JavaScript code, which creates store, grid, e.t.c. is:
Ext.require([
'Ext.grid.*',
'Ext.data.*',
'Ext.util.*',
'Ext.toolbar.Paging',
'Ext.ModelManager',
'Ext.layout.*'
]);
Ext.onReady(function(){
// Define data model
Ext.define('Company', {
extend: 'Ext.data.Model',
fields: [
{
name: 'id',
type: 'int'
},
'name', 'region', 'address',
{
name: 'dealCount',
type: 'int'
},
{
name: 'dealAmount',
type: 'int'
},
{
name: 'latestDealDate',
type: 'string'
}
],
idProperty: 'id'
});
// Create data store
var companies = Ext.create('Ext.data.Store', {
pageSize: 50,
model: 'Company',
proxy: Ext.create('Ext.data.proxy.Ajax', {
url: 'service/companies-data.php'
}),
reader: Ext.create('Ext.data.reader.Json', {
root: 'companies',
totalProperty: 'totalCount'
}),
sorters: [{
property: 'name',
direction: 'ASC'
}]
});
// Create data grid
var grid = Ext.create('Ext.grid.Panel', {
renderTo: Ext.getBody(),
width: 700,
height: 500,
store: companies,
columns: [
{
text: 'Name',
dataIndex: 'name'
},
{
text: 'Region',
dataIndex: 'region'
},
{
text: 'Address',
dataIndex: 'address'
},
{
text: 'Deal Count',
dataIndex: 'dealCount'
},
{
text: 'Deal Amount',
dataIndex: 'dealAmount'
},
{
text: 'Latest Deal Date',
dataIndex: 'latestDealDate'
}
],
bbar: Ext.create('Ext.PagingToolbar', {
store: companies,
displayInfo: true,
displayMsg: 'Displaying topics {0} - {1} of {2}',
emptyMsg: "No topics to display"
})
});
// Load first data page
companies.loadPage(1);
});
Firebug shows, that server responds with json-data, but grid remains empty. How can I fix it?

You should define reader inside proxy (at least that helped for me). Eg:
proxy: Ext.create('Ext.data.proxy.Ajax', {
url: 'service/companies-data.php',
reader: Ext.create('Ext.data.reader.Json', {
root: 'companies',
totalProperty: 'totalCount'
})
})
