This must be a MethodBinding or a String representing the application action to invoke when this component is activated by the user.

The String is directly passed to the Navigationhandler. |
| actionListener | false | true | java.lang.String | MethodBinding representing an action listener method that will be notified when this component is activated by the user. The expression must evaluate to a public method that takes an ActionEvent parameter, with a return type of void. |
| immediate | false | true | java.lang.String | Flag indicating that, if this component is activated by the user, notifications should be delivered to interested listeners and actions immediately (that is, during Apply Request Values phase) rather than waiting until Invoke Application phase. |
| onclick | false | true | java.lang.String | Script to be invoked when clicked |
| link | false | true | java.lang.String | Link to an arbitrary URL |
| transition | false | true | java.lang.String | Specify, if the command calls an JSF-Action. Useful to switch off the Double-Submit-Check and Waiting-Behavior. |

| value | false | true | java.lang.String | The current value of this component. |
| converter | false | true | java.lang.String | An expression that specifies the Converter for this component.

The value can either be a static value (ID case only) or an EL expression. |
