The most common example of an immediate action is a Cancel button. You make it immediate so that the normal validation and update steps can be skipped, but the action handler can still do whatever is necessary. Typically, the action handler will navigate back to some previous page. In some designs the action handler might also enqueue an informational message like "Transaction cancelled". It is possible to do more: for example, an application might record the fact that the user got partially through a form and then cancelled it.

You can bind this property to a variable that determines when the component does get rendered. For example, an airline reservation form might show a component for frequent flyers and not show it for the general public. To bind this property, right-click the component in the Visual Designer and choose Property Bindings, and then select the All radio button to display all properties so you can select the rendered property.
Type: String
tabindex
attribute of the HTML <input>
tag. Type: MethodBinding
MethodBinding
property that underlies the valueChange event property. The valueChangeListener property is updated when you set the method for the valueChange event property.
If you click the ellipsis button next to the valueChange property, you can use that property's property editor to choose an existing method to bind to, or you can create a new method or unbind an existing method. If you are an expert, instead of using the valueChange property, you can type a MethodBinding
expression directly into this valueChangeListener property, for example, if you want to call a method that is not in the page bean.
