</span> * Provides Ext.direct support for submitting form data.
 *
 * This example illustrates usage of Ext.direct.Direct to **submit** 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,
 *         buttons:[{
 *             text: 'Submit',
 *             handler: function(){
 *                 myFormPanel.getForm().submit({
 *                     params: {
 *                         foo: 'bar',
 *                         uid: 34
 *                     }
 *                 });
 *             }
 *         }],
 *
 *         // 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']
 *     });
 *
 * The data packet sent to the server will resemble something like:
 *
 *     {
 *         &quot;action&quot;:&quot;Profile&quot;,&quot;method&quot;:&quot;updateBasicInfo&quot;,&quot;type&quot;:&quot;rpc&quot;,&quot;tid&quot;:&quot;6&quot;,
 *         &quot;result&quot;:{
 *             &quot;success&quot;:true,
 *             &quot;id&quot;:{
 *                 &quot;extAction&quot;:&quot;Profile&quot;,&quot;extMethod&quot;:&quot;updateBasicInfo&quot;,
 *                 &quot;extType&quot;:&quot;rpc&quot;,&quot;extTID&quot;:&quot;6&quot;,&quot;extUpload&quot;:&quot;false&quot;,
 *                 &quot;name&quot;:&quot;Aaron Conran&quot;,&quot;email&quot;:&quot;aaron@sencha.com&quot;,&quot;company&quot;:&quot;Sencha Inc.&quot;
 *             }
 *         }
 *     }
 *
 * The form will process a data packet returned by the server that is similar to the following:
 *
 *     // sample success packet (batched requests)
 *     [
 *         {
 *             &quot;action&quot;:&quot;Profile&quot;,&quot;method&quot;:&quot;updateBasicInfo&quot;,&quot;type&quot;:&quot;rpc&quot;,&quot;tid&quot;:3,
 *             &quot;result&quot;:{
 *                 &quot;success&quot;:true
 *             }
 *         }
 *     ]
 *
 *     // sample failure packet (one request)
 *     {
 *             &quot;action&quot;:&quot;Profile&quot;,&quot;method&quot;:&quot;updateBasicInfo&quot;,&quot;type&quot;:&quot;rpc&quot;,&quot;tid&quot;:&quot;6&quot;,
 *             &quot;result&quot;:{
 *                 &quot;errors&quot;:{
 *                     &quot;email&quot;:&quot;already taken&quot;
 *                 },
 *                 &quot;success&quot;:false,
 *                 &quot;foo&quot;:&quot;bar&quot;
 *             }
 *     }
 *
 * Also see the discussion in {@link Ext.form.action.DirectLoad}.
