-/** - * @class Ext.form.Action - *The subclasses of this class provide actions to perform upon {@link Ext.form.BasicForm Form}s.
- *Instances of this class are only created by a {@link Ext.form.BasicForm Form} when - * the Form needs to perform an action such as submit or load. The Configuration options - * listed for this class are set through the Form's action methods: {@link Ext.form.BasicForm#submit submit}, - * {@link Ext.form.BasicForm#load load} and {@link Ext.form.BasicForm#doAction doAction}
- *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.BasicForm#submit submit}, - * {@link Ext.form.BasicForm#load load} and {@link Ext.form.BasicForm#doAction doAction}), - * and to the {@link Ext.form.BasicForm#actioncomplete actioncomplete} and - * {@link Ext.form.BasicForm#actionfailed actionfailed} event handlers.
