Show_lov with Clear_block

Question

Hi All,
I have two blocks
In first block there are 4 Lovs
Second block has non-database items.
When I select any LOV from 1st block all the values in 2nd block must be clear.
so i used
     If LOV_STATUS=TRUE THEN
     GO_BLOCK('GP_SS_LOC_STATUS');
     CLEAR_BLOCK(NO_VALIDATE);     
     --GO_ITEM('BAL_STATUS');
     END IF;
But, the problem is it is only working whenever i click on Ok button in LOV Button.
Is it possible to clear the below block when click on LOV button?

Answer 1

I created a form with 2 blocks in 9i.
B1 and B2
In b1 I created one text item T1 and for b2 many text items T2, T3...
In the when validate item for T1 I wrote below code
declare
     tm_id timer;
begin
     If :t1 is null then
     tm_id := Find_Timer( 'monk' );
     IF NOT Id_Null(tm_id) THEN
          Delete_Timer(tm_id);
          END IF;
     tm_id:=create_timer('monk',12, NO_REPEAT);
     End if;
end;
In the when timer expired
go_block('B2');
clear_block;
And this code works fine. If you need the sample form let me know your email
