# Class Ext.form.Action.Load

Package: | Ext.form
Defined In: | Action.js
Class: | Action.Load
Extends: | Action

A class which handles loading of data from a server into the Fields of an Ext.form.BasicForm.
Instances of this class are only created by a Form when submitting.
A response packet must contain a boolean `success` property, and a `data` property. The `data` property contains the values of Fields to load. The individual value object for each Field is passed to the Field's setValue method.
By default, response packets are assumed to be JSON, so a typical response packet may look like this:

    {
        success: true,
        data: {
            clientName: "Fred. Olsen Lines",
            portOfLoading: "FXT",
            portOfDischarge: "OSL"
        }
    }

Other data may be placed into the response for processing the the Form's callback or event handler methods. The object decoded from this JSON is available in the result property.
