- * @class Ext.form.action.Action

- * <p>Instances of this class are only created by a {@link Ext.form.Basic Form} when

- * listed for this class are set through the Form's action methods: {@link Ext.form.Basic#submit submit},
- * {@link Ext.form.Basic#load load} and {@link Ext.form.Basic#doAction doAction}</p>
- * <p>The instance of Action which performed the action is passed to the success
- * and failure callbacks of the Form's action methods ({@link Ext.form.Basic#submit submit},
- * {@link Ext.form.Basic#load load} and {@link Ext.form.Basic#doAction doAction}),
- * and to the {@link Ext.form.Basic#actioncomplete actioncomplete} and

/**
+ * @class Ext.Action
+ * <p>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.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.  Each Component below will have the same
+// display text and icon, and will display the same message on click.
+var action = new Ext.Action({
