</span> * Provides {@link Ext.direct.Manager} support for loading form data.
 *
 * This example illustrates usage of Ext.direct.Direct to **load** a form through Ext.Direct.
 *
 *     var myFormPanel = new Ext.form.Panel({
 *         // configs for FormPanel
 *         title: 'Basic Information',
 *         renderTo: document.body,
 *         width: 300, height: 160,
 *         padding: 10,
 *
 *         // configs apply to child items
 *         defaults: {anchor: '100%'},
 *         defaultType: 'textfield',
 *         items: [{
 *             fieldLabel: 'Name',
 *             name: 'name'
 *         },{
 *             fieldLabel: 'Email',
 *             name: 'email'
 *         },{
 *             fieldLabel: 'Company',
 *             name: 'company'
 *         }],
 *
 *         // configs for BasicForm
 *         api: {
 *             // The server-side method to call for load() requests
 *             load: Profile.getBasicInfo,
 *             // The server-side must mark the submit handler as a 'formHandler'
 *             submit: Profile.updateBasicInfo
 *         },
 *         // specify the order for the passed params
 *         paramOrder: ['uid', 'foo']
 *     });
 *
 *     // load the form
 *     myFormPanel.getForm().load({
 *         // pass 2 arguments to server side getBasicInfo method (len=2)
 *         params: {
 *             foo: 'bar',
 *             uid: 34
 *         }
 *     });
 *
 * The data packet sent to the server will resemble something like:
 *
 *     [
 *         {
 *             &quot;action&quot;:&quot;Profile&quot;,&quot;method&quot;:&quot;getBasicInfo&quot;,&quot;type&quot;:&quot;rpc&quot;,&quot;tid&quot;:2,
 *             &quot;data&quot;:[34,&quot;bar&quot;] // note the order of the params
 *         }
 *     ]
 *
 * The form will process a data packet returned by the server that is similar to the following format:
 *
 *     [
 *         {
 *             &quot;action&quot;:&quot;Profile&quot;,&quot;method&quot;:&quot;getBasicInfo&quot;,&quot;type&quot;:&quot;rpc&quot;,&quot;tid&quot;:2,
 *             &quot;result&quot;:{
 *                 &quot;success&quot;:true,
 *                 &quot;data&quot;:{
 *                     &quot;name&quot;:&quot;Fred Flintstone&quot;,
 *                     &quot;company&quot;:&quot;Slate Rock and Gravel&quot;,
 *                     &quot;email&quot;:&quot;fred.flintstone@slaterg.com&quot;
 *                 }
 *             }
 *         }
 *     ]
