The <a4j:ajax> behavior allows Ajax capability to be added to a non-Ajax component. The non-Ajax component must
implement the ClientBehaviorHolder interface for all the event attributes that support behavior rendering.

Attributes |
Name |
Required |
Type |
Description |
bypassUpdates |
false |
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
|
data |
false |
java.lang.Object |
Serialized (on default with JSON) data passed to the client by a developer on an AJAX request. It's accessible via "event.data"
syntax. Both primitive types and complex types such as arrays and collections can be serialized and used with data
|

event |
false |
java.lang.String |
Name of JavaScript event property (click, change, etc.) of parent component that triggers the behavior. If the event attribute
is not defined, the behavior is triggered on the event that normally provides interaction behavior for the parent component
|
execute |
false |
java.util.Collection |
Ids of components that will participate in the "execute" portion of the Request Processing Lifecycle. Can be a single id,
a space or comma separated list of Id's, or an EL Expression evaluating to an array or Collection. Any of the keywords "@this",
"@form", "@all", "@none", "@region" may be specified in the identifier list. Some components make use of additional keywords
|
immediate |
false |
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.
|
limitRender |
false |
boolean |
If "true", render only those ids specified in the "render" attribute, forgoing the render of the auto-rendered panels |
listener |
false |
javax.el.MethodExpression |
MethodExpression 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, or to a public
method that takes no arguments with a return type of void. In the latter case, the method has no way of easily knowing where
the event came from, but this can be useful in cases where a notification is needed that "some action happened".
