Custom Error Message for Validation.....

Question

Here is my Validation:
I want the error which is grown from what is wrong on the page to display after the validation.
the GUI for validation will not let me leave the Validation ERROR box empty...just not sure how to get around this.
DECLARE
isValid BOOLEAN := TRUE;
message VARCHAR2(4000):='';
BEGIN
if (:P14_EXISTING_METRIC_NAME IS NULL and :P14_METRIC_NAME IS NULL)
then
message := 'Metric Name is Not Chosen:';
isValid := FALSE;
end if;
if   (:P14_EXISTING_SUB_VALUE IS NULL and :P14_METRIC_SUBNAME IS NULL)
then
message := message || ' Sub Metric Name is Not Chosen:';
isValid := FALSE;
end if;
if NOT REGEXP_LIKE(:P14_METRIC_VALUE,'expression')
  then
message := message || ' Value is not Numeric:';
  isValid := FALSE;
end if;
if NOT isValid
then
   raise_application_error (-20001,message);
end if;
END;Edited by: bostonmacosx on Feb 27, 2013 12:05 PM

Answer 1

SO what I did was make sure that the process doesn't go false:
and at the end just checked my messages and added an error on the end. WHEW hope this helps someone in the future.
DECLARE
isValid BOOLEAN := TRUE;
message VARCHAR2(4000):=NULL;
BEGIN
if (:P14_EXISTING_METRIC_NAME IS NULL and :P14_METRIC_NAME IS NULL)
then
message := 'Metric Name is Not Chosen<BR>';
end if;
if   (:P14_EXISTING_SUB_VALUE IS NULL and :P14_METRIC_SUBNAME IS NULL)
then
message := message || ' Sub Metric Name is Not Chosen<BR>';
end if;
if (NOT REGEXP_LIKE(:P14_METRIC_VALUE,'^(\d{1,99})\.(\d{0,99})$') or :P14_METRIC_VALUE IS NULL)
  then
message := message || ' Value is not Numeric<BR>';
end if;
if message IS NOT NULL
then
apex_error.add_error (
        p_message          => message,
        p_display_location => apex_error.c_inline_in_notification );
end if;
