Attributes
Name | Required | Request-time | Type | Description
accesskey | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | This attribute assigns an access key to an element. An access key is a single character from the document character set. Note: Authors should consider the input method of the expected reader when specifying an accesskey
action | false | false | `javax.el.MethodExpression` (signature must match `java.lang.Object action()`) | MethodBinding pointing at the application action to be invoked, if this UIComponent is activated by you, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property
actionListener | false | false | `javax.el.MethodExpression` (signature must match `void actionListener(javax.faces.event.ActionEvent)`) | MethodBinding pointing at method accepting an ActionEvent with return type void
ajaxSingle | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | Limits JSF tree processing (decoding, conversion, validation and model updating) only to a component that sends the request. Boolean. Default value is "false".
binding | false | false | `javax.el.ValueExpression` (must evaluate to `javax.faces.component.UIComponent`) | The attribute takes a value-binding expression for a component property of a backing bean
bypassUpdates | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "true", after process validations phase it skips updates of model beans on a force render response. It can be used for validating components input
charset | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The character encoding of a resource designated by this hyperlink
coords | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The attribute specifies shape and it position on the screen. Possible values: "rect: left-x, top-y, right-x, bottom-y", "circle: center-x, center-y, radius", "poly: x1, y1, x2, y2, ..., xN, yN". Notes: a) when giving the radius value in percents, user agents should calculate the final radius value in pixels based on the associated object's width and height; b) the radius value should be smaller than center-x and center-y values; c) for a polygon, the first and last coordinate pairs should have same x and y to close the shape (x1=xN; y1=yN) (when these coordinates are different, user agents should infer an additional pair to close a polygon). Coordinates are relative to the top left corner of an object. All values are lengths. All values are comma separated.
data | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.Object`) | Serialized (on default with JSON) data passed on the client by a developer on AJAX request. It's accessible via "data.foo" syntax

id | false | false | `java.lang.String` | Every component may have a unique id that is automatically created if omitted
ignoreDupResponses | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | Attribute allows to ignore an Ajax Response produced by a request if the newest 'similar' request is in a queue already. ignoreDupResponses="true" does not cancel the request while it is processed on the server, but just allows to avoid unnecessary updates on the client side if the response isn't actual now
immediate | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | True means, that the default ActionListener should be executed immediately (i.e. during Apply Request Values phase of the request processing lifecycle), rather than waiting until the Invoke Application phase
lang | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | Code describing the language used in the generated markup for this component
limitToList | false | false | `javax.el.ValueExpression` (must evaluate to `boolean`) | If "true", then of all AJAX-rendered on the page components only those will be updated, which ID's are passed to the "reRender" attribute of the describable component. "false"-the default value-means that all components with ajaxRendered="true" will be updated.
onbeforedomupdate | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The client-side script method to be called before DOM is updated
onblur | false | false | `javax.el.ValueExpression` (must evaluate to `java.lang.String`) | The client-side script method to be called when the element loses the focus either when pointing a device or tabbing navigation. The attribute may be used with the same elements as onfocus
