Attributes |
Name | Required | Request-time | Type | Description |
forceId | false | false | java.lang.String | If true, this component will force the use of the specified id when rendering. |
forceIdIndex | false | false | java.lang.String | If false, this component will not append a '[n]' suffix
(where 'n' is the row index) to components that are
contained within a "list." This value will be true by
default and the value will be ignored if the value of
forceId is false (or not specified.) |
validator | false | false | java.lang.String | A method binding EL expression, accepting FacesContext, UIComponent,
and Object parameters, and returning void, that validates the
component's local value. |
valueChangeListener | false | false | java.lang.String | A method binding EL expression, accepting a ValueChangeEvent parameter
and returning void. The specified method is invoked if this component
is modified. The phase that this handler is fired in can be controlled
via the immediate attribute. |
immediate | false | false | java.lang.String | A boolean value that identifies the phase during which value change
events should fire. During normal event processing, value change
events are fired during the "process validations" 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. |
required | false | false | java.lang.String | A boolean value that indicates whether an input value is required.
If this value is true, and no input value is provided, the error
message javax.faces.component.UIInput.REQUIRED is posted. |
converter | false | false | java.lang.String | 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. |
value | false | false | java.lang.String | The initial value of this component. This value is generally set as a value-binding in the
form #{myBean.myProperty}, where myProperty can be any data-type of Java (also user-defined
data-types), if a converter for this data-type exists.
Special cases:
1) f:selectItems - value needs to bind to a list (or an array) of
javax.faces.model.SelectItem-instances
2) components implementing UISelectMany (e.g. h:selectManyCheckbox) - value needs to bind to
a list (or an array) of values, where the values need to be of the same data-type as the
choices of the associated f:selectItems-component
3) components implementing UIData (e.g. h:dataTable) - value needs to bind to a list (or an
array) of values, which will be iterated over when the data-table is processed |
id | false | false | java.lang.String | An identifier for this particular component instance within
a component view.
The id must be unique within the scope of the tag's enclosing
NamingContainer (eg h:form or f:subview). The id is
not necessarily unique across all components in the current view
This value must be a static value, ie not change over the lifetime
of a component. It cannot be defined via an EL expression; only
a string is permitted.
|
rendered | false | false | java.lang.String | A boolean value that indicates whether this component should be rendered.
Default value: true. |
binding | false | false | java.lang.String | Identifies a backing bean property (of type UIComponent or appropriate subclass) to bind to this component instance. This value must be an EL expression. |
