LoV = List of Values.
In page.jspx
Either
<h:selectOneChoice binding="#{myBean.mySelector}" value="#{whatever}">
<f:selectItem itemValue="someValue" itemLabel="someText"/>
</h:selectOneChoice>
or
<h:selectOneChoice value="#{whatever}">
<f:selectItems value="#{myBean.listOfValues}"/>
</h:selectOneChoice>
In MyBeanClass.java
Either
public class MyBeanClass
{
private UISelectOne mySelector;
public UISelectOne getMySelector()
{
return mySelector;
}
public void setMySelector(UISelectOne mySelector)
{
this.mySelector = mySelector;
}
public String getSelectedDescription()
{
Object selectedValue = mySelector.getValue();
if (selectedValue == null)
{
return null;
}
for (UIComponent child : (List<UIComponent>)mySelector.getChildren())
{
if (selectedValue.equals(child.getItemValue()))
{
return child.getItemLabel();
}
}
return null; // or throw an exception
}
}
or
public class MyBeanClass
{
private List<SelectItem> listOfValues;
public List<SelectItem> getListOfValues()
{
return listOfValues;
}
public String getSelectedDescription()
{
Object selectedValue = mySelector.getValue();
if (selectedValue == null)
{
return null;
}
for (SelectItem item : listOfValues)
{
if (selectedValue.equals(item.getValue()))
{
return item.getLabel();
}
}
return null; // or throw an exception
}
}
That being said, I'm very curious about the use case requiring that.
