UIInput
and UIOutput Properties
The following tag binds the name component to the name property of CashierBean.
<h:inputText id=
"name" size="50"
value=
"#{cashier.name}"
required=
"true">
<f:valueChangeListener
type=
"com.sun.bookstore6.listeners.NameChanged" />
</h:inputText>
Here is the bean property bound to the name component:
protected String name = null;
public void setName(String name) {
this.name = name;
}
public String getName() {
return this.name;
}
As
describes, to convert the value of a UIInput or
UIOutput
component, you can either apply a converter or create the bean property bound to the
component with the desired type. Here is the example tag explained in
that displays the date books will be shipped:
<h:outputText value=
"#{cashier.shipDate}">
<f:convertDateTime dateStyle=
"full" />
</h:outputText>
The application developer must ensure that the property bound to the component represented
by this tag has a type of java.util.Date. Here is the shipDate property in CashierBean:
