| 23 | * <p> | |
| 24 | * This component is generally only used when the form has multiple submit buttons, and it is | |
| 25 | * important for the application to know which one was pressed. You may also want to use | |
| 26 | * {@link ImageSubmit}which accomplishes much the same thing, but uses a graphic image instead. | |
