Attributes
| Name | Type | Supports EL? | Description |
|---|---|---|---|
| binding | javax.faces.component.html.HtmlInputHidden | Only EL | Identifies a backing bean property (of type UIComponent or appropriate subclass) to bind " + "to this component instance. This value must be an EL expression. |
| converter | javax.faces.convert.Converter | Yes | An expression that specifies the Converter for this component.
The value can either be a static value (ID) or an EL expression. When a static id is specified, an instance of the converter type registered with that id is used. When this is an EL expression, the result of evaluating the expression must be an object that implements the Converter interface. |
| converterMessage | String | Yes | Text to be displayed to the user as an error message when conversion of a submitted value to the target type
fails.
|
| id | String | Yes | Get a string which uniquely identifies this UIComponent within the scope of the nearest ancestor NamingContainer component. The id is not necessarily unique across all components in the current view. |
| immediate | boolean | Yes | A boolean value that identifies the phase during which action events should fire.
During normal event processing, action methods and action listener methods are fired during the "invoke application" phase of request processing. If this attribute is set to "true", these methods are fired instead at the end of the "apply request values" phase. |
| rendered | boolean | Yes | A boolean value that indicates whether this component should be rendered. Default value: true. |
| required | boolean | Yes | A boolean value that indicates whether an input value is required.
If this value is true and no input value is provided by a postback operation, then the "requiredMessage" text is registered as a FacesMessage for the request, and validation fails. Default value: false. |
| requiredMessage | String | Yes | Text to be displayed to the user as an error message when this component is marked as "required" but no input data is present during a postback (ie the user left the required field blank). |
| validator | javax.faces.el.MethodBinding | Only EL | A method-binding EL expression which is invoked during the validation phase for this component.
The invoked method is expected to check the submitted value for this component, and if not acceptable then report a validation error for the component. The method is expected to have the prototype public void aMethod(FacesContext, UIComponent,Object) |
| validatorMessage | String | Yes | Text which will be shown if validation fails. |
| value | Object | Yes | Gets The initial value of this component. |
| valueChangeListener | javax.faces.el.MethodBinding | Only EL | A method which is invoked during postback processing for the current view if the submitted value for this
component is not equal to the value which the "value" expression for this component returns.
The phase in which this method is invoked can be controlled via the immediate attribute. |
