<p>This example shows how to implement a Writer for your Store. A Writer-enabled Store frees you from having to manually compose Ajax requests
to perform CRUD actions on a Store.</p>
-<p>Note that the js is not minified so it is readable. See <a href="writer.js">writer.js</a>, <a href="UserForm.js">UserForm.js</a> and
-<a href="UserGrid.js">UserGrid.js</a>.</p>
+<p>Note that the js is not minified so it is readable. See <a href="writer.js">writer.js</a>.
-<p>The HttpProxy plugged into the store in this example uses the new <em>api</em> configuration instead of an <em>url</em>.
+<p>The AjaxProxy plugged into the store in this example uses the <em>api</em> configuration instead of an <em>url</em>.
A simple MVC-like php backend has been created for this example which simulates a database by storing records in $_SESSION. See the file /remote/app/controllers/users.php. You may have to configure
your web-server to allow scripts to be executed in the /examples directory.</p>
-<code><pre>
-var proxy = new Ext.data.HttpProxy({
- api: {
- read : 'app.php/users/read',
- create : 'app.php/users/create',
- update : 'app.php/users/update',
- destroy : 'app.php/users/destroy'
- }
-});
-</pre></code>

<p>Take note of the requests being generated in Firebug as you interact with the Grid and Form.</p>
-<p>An <b>Error has been simulated</b> on the server-side: Attempting to update a record having ODD-numbered id will generate this errror.
+<p>An <b>Error has been simulated</b> on the server-side: Attempting to update a record having <b>ODD</b>-numbered id will generate this errror.
Responses from the update action will have successProperty === false along with a message. This error can be handled by
-listening to the <b>"exception"</b> event upon your Store.</p>
-
-<code><pre>
-exception : function(proxy, type, action, options, res, arg) {
- if (type === 'remote') {
- Ext.Msg.show({
- title: 'REMOTE EXCEPTION',
- msg: res.message,
- icon: Ext.MessageBox.ERROR
- });
- }
-}
-</pre></code>
-<p><b>Note: This new "exception" event supercedes the old loadexception event which is now deprecated.</b></p>
