Actions let you share handlers, configuration options and UI + * updates across any components that support the Action interface (primarily {@link Ext.toolbar.Toolbar}, {@link Ext.button.Button} + * and {@link Ext.menu.Menu} components).</p> + * <p>Use a single Action instance as the config object for any number of UI Components which share the same configuration. The + * Action not only supplies the configuration, but allows all Components based upon it to have a common set of methods + * called at once through a single call to the Action.</p> + * <p>Any Component that is to be configured with an Action must also support + * the following methods:<ul> + * <li><code>setText(string)</code></li> + * <li><code>setIconCls(string)</code></li> + * <li><code>setDisabled(boolean)</code></li> + * <li><code>setVisible(boolean)</code></li> + * <li><code>setHandler(function)</code></li></ul>.</p> + * <p>This allows the Action to control its associated Components.</p> + * Example usage:<br> + * <pre><code> +// Define the shared Action.

- *Response Packet Criteria
- *A response packet may contain: - *
success property : Boolean
- * success property is required.errors property : Object
- * errors property,
- * which is optional, contains error messages for invalid fields.JSON Packets
- *By default, response packets are assumed to be JSON, so a typical response - * packet may look like this:
-{
- success: false,
- 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}:
- errorReader: new Ext.data.XmlReader({
- record : 'field',
- success: '@success'
- }, [
- '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>
- <msg><![CDATA[Code not found. <br /><i>This is a test validation message from the server </i>]]></msg>

- <id>portOfLoading</id>
- <msg><![CDATA[Port not found. <br /><i>This is a test validation message from the server </i>]]></msg>
- </field>
-</errors>
-</message>
-Other elements may be placed into the response XML for processing by the {@link Ext.form.BasicForm}'s callback - * or event handler methods. The XML document is available in the {@link #errorReader}'s {@link Ext.data.XmlReader#xmlData xmlData} property.
