Messages in on-error coming more than once.

Question

Hi
Iam working in Forms 10g.
Iam over-riding on-error and on-message triggers in my form.
Assume below as my on-error code:
message(error_type || '-' || to_char(error_code));
I have a date item with below code in its key-next-item trigger.
if :blk.item1 > sysdate then
Message('greater than sydate);
end if;
if :blk.item1 < sysdate then
Message('less than sydate);
end if;
Here is my issue:
I run the form and give a negative test case for the date field, ie. enter value 'asdf' for the date field.
Now iam getting on-error fired twice and getting the error message twice. ie. am getting on-error fired as many times i refer the date item in the key-next-item trigger.
But i need to get the error only once and not twice or thrice.
Please suggest me how to solve this.
Thanks

I tried both raise form_trigger_failure as well as return but still am getting on-error firing as many times the field reference in the trigger. We are doing maintenance of client's application and i cannot remove the existing key-next-item functionality.
The client application has lot of validations in key-next-item and post-change. Whenever we face date validations in these triggers, we are getting on-error fired as many times the number of date field reference in the trigger.
Iam trying to fix the issue in on-error itself but i couldn't. As of now i found a work-around which is given below.
In on-error i have below code:
show_alert(error_message);
if error_code in (50025,50026) then
raise form_trigger_failure;
end if;
So when ever i get "Invalid date" error, iam making the form status failure.
In my key-next-item
if :blk.item1 > sysdate then
Message('greater than sydate);
end if;
IF NOT FORM_SUCCESS THEN
RAISE FORM_TRIGGER_FAILURE;
END IF;
if :blk.item1 < sysdate then
Message('less than sydate);
end if;
(Note: The code in upper case is the one that i added newly.
So if i give an invalid date for :blk.item1 iam getting on-error fired, then iam making form status failure, then in key-next-item iam checking if form status is failure then raise. )
This is just an work around but practically it is not possible for me to give this work around in so many triggers, it will be great if i can able to raise the error only 1 time in on-error.
I think i have stated the issue clearly. Please help me to give a fix in on-error itself.
