Dynamically change LOV in oracle apps forms

Question

Hi,
I have one requirement the Item LOV need to change based on the condition. If the condition is X then it use the X record group and attach to the LOV (This record groups is I have already created at design time). I can able to attache the record group to the LOV based on condition but if I click the LOV it not pop up in a window it is simply not working (no error).
If I enter some text in the Item and press Tab then the LOV window is pop up.
Can you please post your suggestion or solutions for this issue.
I am giving my sample code the below code I am using to attache the record group to the LOV.
Item level KEY-LISTVAL Trigger
     Set_ITEM_Property('XXRULES.P_RULE_VALUE',LOV_NAME,'ZIP_CODE');
     Set_ITEM_Property('XXRULES.P_RULE_VALUE',LOV_VALIDATION,PROPERTY_TRUE);
     Set_LOV_Property('ZIP_CODE',GROUP_NAME,'ZIP_CODE');

Answer 1

Set_ITEM_Property('XXRULES.P_RULE_VALUE',LOV_NAME,'ZIP_CODE');Set_ITEM_Property('XXRULES.P_RULE_VALUE',LOV_VALIDATION,PROPERTY_TRUE);
Set_LOV_Property('ZIP_CODE',GROUP_NAME,'ZIP_CODE'); Is this all of your code? If so, you are missing the call to Show_LOV(). Remember, Show_LOV() returns a boolean so you have to catch the return value.
DECLARE
   b_selected  BOOLEAN := FALSE;
BEGIN
   Set_ITEM_Property('XXRULES.P_RULE_VALUE',LOV_NAME,'ZIP_CODE');
   Set_ITEM_Property('XXRULES.P_RULE_VALUE',LOV_VALIDATION,PROPERTY_TRUE);
   Set_LOV_Property('ZIP_CODE',GROUP_NAME,'ZIP_CODE');
   b_selected := Show_LOV('ZIP_CODE');
END;Hope this helps,
