[Solved] Changing tab visibility

Question

Hi all,
I have some problems with Forms6i and I'm hopping someone could help me...
I have a form with 3 tabs. In the 1st tab I have several fields and depending on the value of one of those fields I want my 3rd tab to be visible or invisible.
My only problem with this is that after the situation: invisible -> visible, it doesn't change back to invisible.
I search it on the net and found something similarly to this but with text boxes and I tried the same resolutions on the tab but the properties aren't the same.
If anyone could help me, I appreciated.
Thanks,
Ana

Answer 1

I did what you suggested, but still isn't working:
1 - created a simple procedure:
PROCEDURE SET_TAB_VISIBILITY (
P_TAB_NAME      IN VARCHAR2,
P_VISIBLE      IN BOOLEAN
) IS
BEGIN
if P_VISIBLE then
SET_TAB_PAGE_PROPERTY(P_TAB_NAME,visible, property_true);     
else
SET_TAB_PAGE_PROPERTY(P_TAB_NAME,visible, property_false);     
end if;     
END;
2 - deleted the post-change event that I previously created;
3 - on data block level, in the post-query event called the procedure:
SET_TAB_VISIBILITY('FILTROS.PED_SERV', :JE_UBS_IP_MULTI_MESSAGES.event = 'PS');
4 - and on item level, in the when-validate-item also called the procedure with the same code.
I put some messages on the post-query and when-validate-item events to check things out and noticed that when I have something like 2 records and in the 1st one the tab should be invisible and in the 2nd, visible, when I go from record 1 to 2, it changes the visibility correctly and shows my test message. But when I navigate from record 2 to 1, it doesn’t do anything. Not even my message. It seems that it is ignoring the event.
Is this normal behavior?
Thank you
