在selectItems 中使用Binding属性

<h:selectOneMenu       immediate="true"    value="#{myBean.bank}">
	<f:selectItems binding="#{myBean.banks}" />
</h:selectOneMenu>

 

public class MyBean{
 
private UISelectItems banks;
 private  String  bank; 
 
 
public String getBank() {
	return bank;
}

public void setBank(String bank) {
	this.bank = bank;
}

public UISelectItems getBanks(){
  if(banks==null){
    banks = new UISelectItems();
    List selectItems = new ArrayList();
    selectItems.add(new SelectItem("key", "value"));
    banks.setValue(selectItems);
  }
  return banks;
}
 
public void setBanks(UISelectItems banks){
  this.banks=banks;
}
 
}
