/**
+ * @class Ext.form.action.DirectLoad
+ * @extends Ext.form.action.Load
+ * <p>Provides {@link Ext.direct.Manager} support for loading form data.</p>
+ * <p>This example illustrates usage of Ext.direct.Direct to <b>load</b> a form through Ext.Direct.</p>
+ * <pre><code>
+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
+ }
+});
+ * </code></pre>
+ * The data packet sent to the server will resemble something like:
+ * <pre><code>
+[
+ {
+ "action":"Profile","method":"getBasicInfo","type":"rpc","tid":2,
+ "data":[34,"bar"] // note the order of the params
+ }
+]
+ * </code></pre>
+ * The form will process a data packet returned by the server that is similar
+ * to the following format:
+ * <pre><code>
+[
+ {
+ "action":"Profile","method":"getBasicInfo","type":"rpc","tid":2,
+ "result":{
+ "success":true,
+ "data":{
+ "name":"Fred Flintstone",
+ "company":"Slate Rock and Gravel",
+ "email":"fred.flintstone@slaterg.com"
+ }
+ }
+ }
+]
+ * </code></pre>
