    Default How to figure out that the data has been loaded is some rows when using operation

    How to figure out that the data has been loaded is some rows when using Ext.data.operation and ajaxProxy?

    the code is here:

    Ext.define('Book', {
    extend: 'Ext.data.Model',
    fields: [
    {name: 'id', type: 'int'},
    {name: 'title', type: 'string'},
    {name: 'pages', type: 'int'},
    {name: 'numChapters', type: 'int'}
    ]
    });

    var ajaxProxy = Ext.create('Ext.data.proxy.Ajax', {
    url: 'books.json',
    model: 'Book'
    });

    var operation = Ext.create('Ext.data.Operation', {
    action: 'read',
    start: 0,
    limit: 5
    });

    operation.read();

    books.json contains 6 rows, when i try the code bellow, i get 6 rows, when i expected its load 5 rows.

    ajaxProxy.read(operation, function () {
    console.log(operation.response.responseText);
    });

    Default

    Did you look at the response? If the response sends back 6 it will use 6. The limit config is just for what it sends in the request.
