Attributes
Name	Required	Request-time	Type	Description
accessKey	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.Character`)	** @deprecated. Will be removed in a future version ** Deprecated! Has not longer any function. Type: `java.lang.Character`
action	false	false	`javax.el.MethodExpression` (signature must match `java.lang.Object action()`)	Action to invoke when clicked. This must be a MethodBinding or a String representing the application action to invoke when this component is activated by the user. The MethodBinding must evaluate to a public method that takes no parameters, and returns a String (the logical outcome) which is passed to the NavigationHandler for this application. The string is directly passed to the navigation handler.
actionListener	false	false	`javax.el.MethodExpression` (signature must match `void actionListener(javax.faces.event.ActionEvent)`)	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.
binding	false	false	`javax.el.ValueExpression` (must evaluate to `javax.faces.component.UIComponent`)	The value binding expression linking this component to a property in a backing bean. Warning: For the tobago extension library tx the binding differs from JSP and Facelets: JSP: The component is the inner main control (e. g. UIInput). Facelets: The component is the outer UIPanel. Type: `javax.faces.component.UIComponent`
disabled	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.Boolean`)	Flag indicating that this element is disabled. Type: `boolean` Default: `false`
id	false	true	`java.lang.String`	The component identifier for this component. This value must be unique within the closest parent component that is a naming container. Type: `java.lang.String`
image	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.String`)	Url to an image to display. Type: `java.lang.String`
immediate	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.Boolean`)	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. Type: `boolean` Default: `false`
inline	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.Boolean`)	** @deprecated. Will be removed in a future version ** This should be handled by e.g. a flow layout manager (since 1.5.0) Flag indicating this component should rendered as an inline element. Type: `boolean` Default: `false`
jsfResource	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.Boolean`)	Flag indicating that the resource referenced by the resource attribute is a jsf resource. That means that the url has to be processed to change the prefix or suffix (e. g. .jsf or /faces/). Default is false. Type: `boolean` Default: `false`
label	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.String`)	Text value to display as label. If text contains an underscore the next character is used as accesskey. Type: `java.lang.String`
labelWithAccessKey	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.String`)	** @deprecated. Will be removed in a future version ** Deprecated! Use 'label' instead. Text value to display as label. If text contains an underscore the next character overwrites 'accesskey'. Type: `java.lang.String`
link	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.String`)	Link to an arbitrary URL, either an internal link or an external link. internal absolute link Starts with a slash '/' character. The context path will be added. A session id will be added, if needed. external link Contains a colon ':' character. The link will not be modified. internal relative link Any other strings. A session id will be added, if needed. Type: `java.lang.String`
markup	false	false	`javax.el.ValueExpression` (must evaluate to `org.apache.myfaces.tobago.context.Markup`)	Indicate markup of this component. The allowed markups can be defined or overridden in the theme. The value 'none' should not be used any longer. Just leave the attribute empty, or use a NULL pointer. Type: `org.apache.myfaces.tobago.context.Markup`
omit	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.Boolean`)	Flag indicating that the action of this element, will not be executed from client side (e. g. when the user clicks a button. When setting this value to true, the action will not be executed by the Tobago, but it can executed by JavaScript. This attribute is useful, when you want to add JavaScript event handlers to commands manually. In this case you usually don't want a submit with a full reload of the page. Type: `boolean` Default: `false`
onclick	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.String`)	Script to be invoked when clicked Type: `java.lang.String`
rendered	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.Boolean`)	Flag indicating whether or not this component should be rendered (during Render Response Phase), or processed on any subsequent form submit. Type: `boolean` Default: `true`

E. g. define help.html and it will be served help_es.html or help_de.html if available. For JSF-Pages you have to set the jsfResource attribute. Type: `java.lang.String`
tabIndex	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.Integer`)	Controls the navigation of the focus through the input controls on a page with the Tab-Key. The navigation starts from the element with the lowest tabIndex value to the element with the highest value. Elements that have identical tabIndex values should be navigated in the order they appear in the character stream Elements that are disabled or with a negative tabIndex do not participate in the tabbing order. Type: `java.lang.Integer`
target	false	false	`javax.el.ValueExpression` (must evaluate to `java.lang.String`)	Name of a frame where the resource retrieved via this hyperlink is to be displayed. Type: `java.lang.String`
