Output

Creates output text that cannot be modified by the user. The text can be static or bound to a data source. Output components can display data from a data source as well as to display static text within most other Faces components (for example, as a label for an input field). Output can be in the following formats: String, Number, Date/Time, and Mask.

Properties and All Attributes views

The Properties view for a component shows the most common set of attributes you can set on a component, and, depending on the component, you might also see options for adding controls, actions, or other components. To open the Properties view, click

Window | Show View | Properties.

These common attributes for the Output component display on the h:outputText, Validation, Behavior, and Accessibility tabs in the Properties view. See the All Output attributes view table for a complete list of attributes. Additional configuration options to validate input, modify behavior, configure output format types are on the h:outputText>Validation, h:outputtText>Behavior, and h:outputtText tabs:

Table 1. Output configuration options

Configuration option	Description
Auto-advance to next field	Specifies whether auto-tabbing is enabled or disabled. Automatically advances user to another input field after the specified number of characters has been entered. When checked adds the hx:inputHelperAssist section to the All Attributes view and sets autoTab to True.
Click to create/edit custom validation code	Switches to the Quick Edit view so that scripts or snippets of code may be entered for various user initiated events.
Constraint	Limits the type of characters that can be entered into the component (for example, Digits Only or ASCII Alphabet Only). Adds hx:validateConstraint with the regex attribute to the All Attributes view.
Display validation error messages in an error message control	Inserts an error message component associated with the selected component. This will display an error message if the validation fails.
Maximum length	The maximum number of characters this component can contain when submitted on the server. Adds the function f:validateLength with a maximum attribute to the All Attributes view.
Minimum length	The minimum number of characters this component can contain when submitted on the server. Adds a function f:validateLength with a minimum attribute to the All Attributes view.
Validate field value in the browser	Allows for the field validation to happen in the browser at runtime.

Table 2. Output format types configuration options

Configuration option	Description
Format: String	h:outputText tab: Id Value Style: Props Style: Classes Render the HTML in the value
Format: Number	h:outputText tab: Id Value Style: Props Style: Classes Type: Decimal Options Integer only Type: Currency Options Integer only Currency Symbol Type: Percent Options Integer Only Type: Custom Options Pattern
Format: Date/Time	h:outputText tab: Id Value Style: Props Style: Classes Type: Date only Options Date style Type: Time only Options Time style Type: Date and time Options Date style Time style
Format: Mask	h:outputText tab: Id Value Style: Props Style: Classes Options Mask

The All Attributes view shows a table of all the attributes you can set on a component, which includes those attributes you can access from the Properties view. To switch to the All Attributes view, click the

All Attributes icon in the upper right corner of the Properties view.

Table 3. All Output attributes

Attribute name	Represented in Properties view by	Description
accesskey	Accessibility>Access Key	Specifies a single keyboard key as an access key. Pressing the specified access key at runtime gives focus to this component. Pressing ALT plus the specified access key at runtime gives focus to this component (or executes the component if it is a kind of button).
alt	Not represented	Specifies alternate text for a component. The alternative text is displayed when the element cannot be rendered normally, for example, in browsers that do not support forms and in browsers set to not display images.
binding	Not represented	An expression that binds the component's instance (usually a user interface component) to a bean property (usually in the backing file).
converter	Not represented	Specifies the data type to which the value is converted. The JavaServer Faces implementation provides a set of Converter implementations that you can use to convert your component data to a type not supported by its renderer.
dir	Not represented	Specifies the component's direction when rendered at runtime. The values can be either: ltr - left to right rtl - right to left If the direction is not specified, a direction appropriate to the encoding of the component is used.
disabled	Behavior>Control is disabled	If disabled is set to true, the component is displayed at runtime but is not functional. If left blank, the default value is false.
id	ID	Assigns a name to a component. Should be a unique name within a JSP.
immediate	Not represented	If true, skip straight to render phase of life cycle.
lang	Not represented	The language of the component's value(s) and text content. If omitted, the language is inherited from the containing tags (notably the view. Specified as an ISO-standard language abbreviation code. For example, "en" for English, "en-US" for American English, "fr" for French, "de" for German. Note: This does not "translate" the text in the component, rather, it identifies the language of the component so that operations such as searching, sorting, collating and the like are done correctly.
maxlength	Behavior>After user types X characters	Enact the control attribute after an end user enters this many characters into the component.
readonly	Behavior>Control is read-only	Specifies that the value of the component cannot be changed from its initial value.
rendered	Not represented	Can be set to true or false: false - Component will not be rendered to the browser at runtime. true - Component will get rendered. This is the default value.
required	Validation>Value is Required	The component must be specified. Check this to require the user to enter a value.
size	Size: Width	Specifies the initial width of the component, where its value refers to the number of characters.
style	Style: Props	Specifies CSS style information for the component (for example, style="font-size : 8pt ; color : red"). Defines the properties (such as font and color) of the selected component. This may be done manually, or by clicking the button and selecting the desired properties from within the window.
styleClass	Style: Classes	Space-separated list of CSS style classes to be applied when this element is rendered. This value must be passed through as the class attribute on generated markup. Defines the classes (such as style sheets) of the selected component. This may be done manually, or by clicking the button and selecting the desired Classes from within the window.
tabindex	Accessibility>Tab order index	Specifies the position of the component in the tabbing order in the JSP. This value must be a number between 0 and 32767.
title	Accessibility>Title	Specifies the title text, shown in browser as a tooltip at runtime. Used by a browser as the alternative text of a component if the alternative text is not specified.
validator	Not represented	Classname of validator to instantiate.
value	Value	Specifies the initial text value for the component displayed at runtime. Contains information to be displayed, in the form of a specified value or a pointer to a dynamic value.
valueChangeListener	Not represented	Method to be notified when value of component has changed.
