<p>This example illustrates usage of Ext.Direct to <b>load</b> a form through Ext.Direct.</p>
<pre><code><b>var</b> myFormPanel = <b>new</b> Ext.form.FormPanel({
    <i>// configs <b>for</b> FormPanel</i>
    title: <em>'Basic Information'</em>,
    renderTo: document.body,
    width: 300, height: 160,
    padding: 10,

    <i>// configs apply to child items</i>
    defaults: {anchor: <em>'100%'</em>},
    defaultType: <em>'textfield'</em>,
    items: [{
        fieldLabel: <em>'Name'</em>,
        name: <em>'name'</em>
    },{
        fieldLabel: <em>'Email'</em>,
        name: <em>'email'</em>
    },{
        fieldLabel: <em>'Company'</em>,
        name: <em>'company'</em>
    }],

    <i>// configs <b>for</b> BasicForm</i>
    api: {
        <i>// The server-side method to call <b>for</b> load() requests</i>
        load: Profile.getBasicInfo,
        <i>// The server-side must mark the submit handler as a <em>'formHandler'</em></i>
        submit: Profile.updateBasicInfo
    },
    <i>// specify the order <b>for</b> the passed params</i>
    paramOrder: [<em>'uid'</em>, <em>'foo'</em>]
});

<i>// load the form</i>
myFormPanel.getForm().load({
    <i>// pass 2 arguments to server side getBasicInfo method (len=2)</i>
    params: {
        foo: <em>'bar'</em>,
        uid: 34
    }
});</code></pre>
The data packet sent to the server will resemble something like:
<pre><code>[
    {
        <em>"action"</em>:<em>"Profile"</em>,<em>"method"</em>:<em>"getBasicInfo"</em>,<em>"type"</em>:<em>"rpc"</em>,<em>"tid"</em>:2,
        <em>"data"</em>:[34,<em>"bar"</em>] <i>// note the order of the params</i>
    }
]</code></pre>
The form will process a data packet returned by the server that is similar
to the following format:
<pre><code>[
    {
        <em>"action"</em>:<em>"Profile"</em>,<em>"method"</em>:<em>"getBasicInfo"</em>,<em>"type"</em>:<em>"rpc"</em>,<em>"tid"</em>:2,
        <em>"result"</em>:{
            <em>"success"</em>:true,
            <em>"data"</em>:{
                <em>"name"</em>:<em>"Fred Flintstone"</em>,
                <em>"company"</em>:<em>"Slate Rock and Gravel"</em>,
                <em>"email"</em>:<em>"fred.flintstone@slaterg.com"</em>
            }
        }
    }
