Hi all,

thanks

Hello Daniel,

I don't really understand your question. Can you be a bit more specific? If I understand well though, you could either change the value property of your SelectItem object, or loop through the SelectItem list until you find the one with the selected value to extract the description.

Ah ok,

It depends on the type of LoV you're using. If you're using a static lov (<f:selectItem/>;), then you have to use a binding for your selectOneChoice component to your managed bean. Then, in your method, you simply have to loops through the selectOneMenu's children until you find the right UISelectItem. IF you use a dynamic LoV, it's simpler, as you simply have to call the methods returning the list of values and loops through all returned SelectItem objects.

LoV = List of Values.

In page.jspx
Either
<h:selectOneChoice binding=&quot;#{myBean.mySelector}" value=&quot;#{whatever}">;
  <f:selectItem itemValue="someValue" itemLabel="someText"/&gt;
</h:selectOneChoice>
or
<h:selectOneChoice value=&quot;#{whatever}">;
&nbsp; <f:selectItems value=&quot;#{myBean.listOfValues}"/&gt;
</h:selectOneChoice>

In MyBeanClass.java
Either
public class MyBeanClass
{
  private UISelectOne mySelector;

  public UISelectOne getMySelector()
  {
 &nbsp;  return mySelector;
  }

  public void setMySelector(UISelectOne mySelector)
  {
 &nbsp;  this.mySelector = mySelector;
  }

  public String getSelectedDescription()
  {
 &nbsp;  Object selectedValue = mySelector.getValue();
 &nbsp;  if (selectedValue == null)
&nbsp; &nbsp; {
 &nbsp; &nbsp;  return null;
&nbsp; &nbsp; }

 &nbsp;  for (UIComponent child : (List<UIComponent&gt;) mySelector.getChildren())
 &nbsp;  {
 &nbsp; &nbsp;  if ( selectedValue.equals(child.getItemValue()))
 &nbsp; &nbsp;  {
&nbsp; &nbsp; &nbsp; &nbsp; return child.getItemLabel();
 &nbsp; &nbsp;  }
 &nbsp;  }
 
 &nbsp;  return null; // or throw an exception
  }
}
or
public class MyBeanClass
{
  private List<SelectItem>; listOfValues ;

  public List<SelectItem>; getListOfValues()
  {
 &nbsp;  return listOfValues ;
  }

&nbsp; public String getSelectedDescription()
 ; {
 &nbsp;  Object selectedValue = mySelector.getValue();
 &nbsp;  if (selectedValue == null)
   ; {
   ; &nbsp; return null;
&nbsp; &nbsp; }

&nbsp; &nbsp; for (SelectItem item : listOfValues)
   ; {
   ; &nbsp; if (selectedValue.equals(item.getValue()))
 &nbsp; &nbsp;  {
   ; &nbsp; &nbsp; return item.getLabel();
&nbsp; &nbsp;   }
   ; }
 
 &nbsp;  return null; // or throw an exception
  }
}

That being said, I'm very curious about the use case requiring that.
