Trigger Firing Sequence?

Question

Hei Guys
I have a form where I have a date and time field(text fields). I have a OK/SAVE button, which is subclassed, and executes do_key(commit_form), which in turn executes form level key-commit trigger. On the key-commit trigger, I have some program units, which basically validate the form, and then commit the form.
On the time field, if I change the time(which the system calculated when I hit a button), I do some validation in the when-validate-item of the field.
The code in the time text-fields, when-validate-item is as follows.
fp_check_time(:BL_COMPLAINT.APPT_TIME);
declare
     lnu_error number;
     alrt_id alert := find_alert('AL_CONFIRM');
     some_number number;
begin
     --some_number := fpkg_error_handler.fp_message('UEM','0000','ERROR','@when-validate APPT_TIME');
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_true);     
     if :BL_COMPLAINT.APPT_time <> nvl(:parameter.APPT_TIME, '*')     then
set_alert_property(alrt_id, alert_message_text, 'You have changed the system recommended date. This could lead to double booking. Do you want to continue ?');
if show_alert(alrt_id) = ALERT_BUTTON1 then
if spkg_med_schedule.sf_chk_valid_datetime
          (:BL_COMPLAINT.SICK_CALL_SERVICE_GROUP,
'1',--check nurse
:parameter.p_clinic,
:BL_COMPLAINT.APPT_DATE,
:BL_COMPLAINT.APPT_time) = 'N' THEN
     lnu_error := FPKG_ERROR_HANDLER.FP_MESSAGE('UEM','0000','ERROR','The date/time you have selected is not valid. Please change the date/time.');
     :BL_COMPLAINT.APPT_TIME := :parameter.APPT_TIME;
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_false);
      raise form_trigger_failure;
end if;
else
          some_number := fpkg_error_handler.fp_message('UEM','0000','ERROR','@when-vaidate APPT_TIME not ab1');          
     :BL_COMPLAINT.APPT_TIME := :parameter.APPT_TIME;
--     :parameter.error_occur := 'TRUE';
     --set_item_property('bl_ok_cancel.pb_ok', enabled, property_false);
     raise form_trigger_failure;      end if;
end if;     
end;
I have this code even in the date field. which is also a text item.
I am hoping you might have noticed, a couple of Raise form_trigger_failure in the code. But, the processing, does not stop there and continues processing and tries to commit the form.
[b1.]Why does that happen?

> continues processing and tries to commit the form
It would help if you would describe what you mean by "tries to commit". What does the form do?
The first thing you need to do in your commit processing sequence is:
  Validate(form_scope);
  If not form_success then
    Raise form_trigger_failure;
  End if;The above code will stop the commit if an edit error occurs. If you don't validate and check for success, commit processing continues, and you will probably get multiple error messages popping up before the commit process finally stops.
