/** - * @class Ext.Action - *

An Action is a piece of reusable functionality that can be abstracted out of any particular component so that it - * can be usefully shared among multiple components. Actions let you share handlers, configuration options and UI - * updates across any components that support the Action interface (primarily {@link Ext.Toolbar}, {@link Ext.Button} - * and {@link Ext.menu.Menu} components).

- *

Aside from supporting the config object interface, any component that needs to use Actions must also support - * the following method list, as these will be called as needed by the Action class: setText(string), setIconCls(string), - * setDisabled(boolean), setVisible(boolean) and setHandler(function).

- * Example usage:
- *

-// Define the shared action.  Each component below will have the same
-// display text and icon, and will display the same message on click.
-var action = new Ext.Action({
-    {@link #text}: 'Do something',
-    {@link #handler}: function(){
-        Ext.Msg.alert('Click', 'You did something.');
-    },
-    {@link #iconCls}: 'do-something',
-    {@link #itemId}: 'myAction'
-});
-
-var panel = new Ext.Panel({
-    title: 'Actions',
-    width: 500,
-    height: 300,
-    tbar: [
-        // Add the action directly to a toolbar as a menu button
-        action,
-        {
-            text: 'Action Menu',
-            // Add the action to a menu as a text item
-            menu: [action]
-        }
-    ],
-    items: [
-        // Add the action to the panel body as a standard button
-        new Ext.Button(action)
-    ],
-    renderTo: Ext.getBody()
-});
-
-// Change the text for all components using the action
-action.setText('Something else');
-
-// Reference an action through a container using the itemId
-var btn = panel.getComponent('myAction');
-var aRef = btn.baseAction;
-aRef.setText('New text');

Response Packet Criteria

+ *

A response packet may contain: + *

+ *

JSON Packets

+ *

By default, response packets are assumed to be JSON, so a typical response + * packet may look like this:

+    errors: {
+        clientCode: "Client not found",
+        portOfLoading: "This field must not be null"

+ *

Other data may be placed into the response for processing by the {@link Ext.form.BasicForm}'s callback + * or event handler methods. The object decoded from this JSON is available in the + * {@link Ext.form.Action#result result} property.

+ *

Alternatively, if an {@link #errorReader} is specified as an {@link Ext.data.XmlReader XmlReader}:

+            'id', 'msg'
+        ]
+    )
+
+ *

then the results may be sent back in XML format:


+<?xml version="1.0" encoding="UTF-8"?>
+<message success="false">
+<errors>
+    <field>
+        <id>clientCode</id>
