Key-entqry issue

Question

Hi,
I have a form with 2 tabs. After querying some data, If I press ent_qry button, nothing happens. So I wrote the following code in the form_level key-entqry trigger.
BEGIN
   SET_MENU_ITEM_PROPERTY ('QUERY.CANCEL_QUERY', enabled, property_true);
   SET_MENU_ITEM_PROPERTY ('ACTION.SAVE', enabled, property_false);
   clear_form(ask_commit);
   enter_query;
   enable_button('exceptional_events.screening_group_num_btn');
END;
PROCEDURE enable_button(p_field IN VARCHAR2) IS
BEGIN
     IF GET_ITEM_PROPERTY (p_field, enabled) = 'FALSE' THEN
         SET_ITEM_PROPERTY (p_field, enabled, property_true);
   END IF;
   IF GET_ITEM_PROPERTY (p_field, navigable) = 'FALSE' THEN
         SET_ITEM_PROPERTY (p_field, navigable, property_true);
   END IF;
END;the form goes in enter_query mode, but the screening_group_num button is not enabled. Therefore I added the call to enable_button routine. But it does not help.
I tried using call_form('form_name') to see if that enabled the buttons (because when u initially enter the form ( u are in enter_query mode) the button should be enabled. It is disabled in block-level Post-query trigger if data is found, as the user should not be able to modify the key items. The field to which is button is attached is also disabled in post-query trigger, but surprisingly only the button is disabled when u press ent-qry and the field is enabled. )
Any suggestions!!
PS:- Should I just put a DB side constraint that the key-items shoud not be changed (then I would not need to disable and enable the buttons)?
the block is a DB block. but the items which should not be modified are not part of primary key but unique key, therefore we do not have any constraint on DB side.

Hi!
Change to:
BEGIN
SET_MENU_ITEM_PROPERTY ('QUERY.CANCEL_QUERY', enabled, property_true);
SET_MENU_ITEM_PROPERTY ('ACTION.SAVE', enabled, property_false);
clear_form(ask_commit);
enable_button('exceptional_events.screening_group_num_btn');
enter_query;
END;because with the call to enter_query the forms stops to execute the code in the trigger.
RegardsThanks Magoo
Its works now. I found out that there was anothe key-entqry trigger on a datablock which had a call to
enter_query;
enable_button('exceptional_events.screening_group_num_btn'); in that sequence..
now it works fine!
thanks
