Set a component visible based on a value of a LOV

Question

Hi all,
I am using Jdeveloper 11.1.1.2 and ADFBC.
I have a panelFormLayout with some fields.
I have a LOV and I want to set the property visible of a field based on the value of the LOV.
For example: if LOV = First (value =1) field = visible, if LOV = Second (value =1) field = not visible
I have created a backing bean of the page with a method that return a boolean, but I don't know how to get the value of the LOV.
What have I to use? ADFUtils? JSFUtils?
Here there is my code:
public class InsMovimento {
private RichSelectOneChoice soc3;
public void setSoc3(RichSelectOneChoice soc3) {
this.soc3 = soc3;
public RichSelectOneChoice getSoc3() {
return soc3;
public boolean isVisiblePanelLottoEScadenza(){
boolean isVisible = false;
// ... code to retrieve the value of the LOV
return isVisible;
Any suggestions?
Thank you
Andrea

Hi,
you have 2 options. For both options you need to set autosubmit=true on the LOV field and use the PartialTriggers property on the depedent fields to point to the ID of the LOV. Alo define a value change listener on the LOV field
Option 1: Create a managed bean reference for the LOV using its binding property. Then, call getValue on it to get the component value
Option 2: If the component is bound to ADF, you can read the value fom the ADF binding layer
Option 1 is good to use if for example the "immediate" property on the LOV is set to true so you avoid required field validation problems if the dependent fields have no value though must have one. In this case using a ValueChangeListener on the LOV can be used to read the values, and set the boolean values in the managed bean
