Raise form trigger failure does not terminate processing

Question

There is a field in my form, on which there is a when-validate-item trigger, which cheks that the value in the field should be selected from list of values(LOV). If not done that way, error message is displayed.
This works fine, when I enter a value myself and navigate to the next field, it throws an error. This is fine.
But, problem occurs when I enter a value in the field and without navigating to the next field, I press Save(commit).
When this is done - Key commit is invoked, which inturn invokes when-validate-item and erros is displayed. But when
I press the Ok button, the error is displayed again and again. I have to close down the form to get out of it.
In case of error, I have displayed the error and raised form_trigger_failure.
I do not understand why form_trigger_failure terminates processing when I navigate to next field and does not terminate processing when I directly press Save(Commit)?

Answer 1

find the code in When validate item trigger below. I don't much of code in key commit. It does not do anything with the field in question.
DECLARE
l_lov_indicator VARCHAR2(20);
BEGIN
     IF :abc.code IS NOT NULL THEN
          -- If global is not initialized, that means that the value in
          -- code is not fetched from List Of Values and an error
          -- (FRM-40815) is raised. This error is handled in on-error
          -- trigger in Aon block.
          l_lov_indicator := :GLOBAL.lov_indicator;
          -- If global is initialized, the value in code
          -- is fetched from List Of Values and everything is ok.
          -- Otherwise, an error message is displayed.
          IF l_lov_indicator = 'TRUE' THEN
               ERASE('GLOBAL.lov_indicator');
          ELSE
               ERASE('GLOBAL.lov_indicator');
          raise form_trigger_failure;
          END IF;
     END IF;
END;
