Misleading error messages in Apex

Question

Hello all,
I am looking at default values. I simply want to go to the database, call a functin and set the value using PL/SQL Function Body. Here is what happens:
Check in SQL*Plus first ...
blast:Blast-Bld@ORCL> delete blast_log;
6 rows deleted.
blast:Blast-Bld@ORCL> commit;
Commit complete.
blast:Blast-Bld@ORCL> select W_REG.GET_MONTHLY_FEE(1000) from dual;
W_REG.GET_MONTHLY_FEE(1000)
39.95
1 row selected.
blast:Blast-Bld@ORCL> @log
MDL UNT Typ MSG
W_REG GET_MONTHLY_FEE I Begin
REG IS_VALID I Begin
REG IS_VALID D Check Reg ID: 1000 Found 1 row(s). (1 = True else False).
REG IS_VALID I End
W_REG GET_MONTHLY_FEE D Return Reg Fee: 39.95
W_REG GET_MONTHLY_FEE I End
6 rows selected.
blast:Blast-Bld@ORCL> delete blast_log;
6 rows deleted.
blast:Blast-Bld@ORCL>
Now run Apex:
Get the following message:
ORA-01403: no data found
ERR-9131 Error in PLSQL function body for item default code, item=P1000_MONTHLY_FEE
Return to application.
Look at item P1000_MONTHLY_FEE ...
Default = RETURN W_REG.GET_MONTHLY_FEE(1000);
Type = PL/SQL Function Body.
Look in database logging table:
MDL UNT Typ MSG
CODE GET_CODE_SET_ID I Begin
CODE GET_CODE_SET_ID D Get Code Set ID for PersSalut
CODE GET_CODE_SET_ID I End
Function was not called!!!!
To be absolutely sure, call again from SQL*Plus with cut and paste ....
blast:Blast-Bld@ORCL> select W_REG.GET_MONTHLY_FEE(1000) from dual;
W_REG.GET_MONTHLY_FEE(1000)
39.95
1 row selected.
blast:Blast-Bld@ORCL> @log
MDL UNT Typ MSG
CODE GET_CODE_SET_ID I Begin
CODE GET_CODE_SET_ID D Get Code Set ID for PersSalut
CODE GET_CODE_SET_ID I End
W_REG GET_MONTHLY_FEE I Begin
REG IS_VALID I Begin
REG IS_VALID D Check Reg ID: 1000 Found 1 row(s). (1 = True else False).
REG IS_VALID I End
W_REG GET_MONTHLY_FEE D Retunr Reg Fee: 39.95
W_REG GET_MONTHLY_FEE I End
9 rows selected.
blast:Blast-Bld@ORCL>
Looks Fine.
Thus the message returned from Apex is misleading to say the leaset.
Any ideas?

Thanks guys,
(Note that LG is a logging package)
Note also that the reg id is checked first (IS_VALID) to avoid NDF exception.
But what prompted me to make the post is not so much the function, but rather that the message from apex is not very helpful .... unless I'm missing something.
thanks again.
here is the function:
FUNCTION GET_MONTHLY_FEE (p_reg_id REGISTRATIONS.REG_ID%TYPE)
RETURN REGISTRATIONS.MONTHLY_FEE%TYPE IS
l_monthly_fee REGISTRATIONS.MONTHLY_FEE%TYPE;
BEGIN
LG.PUSH('W_REG', 'GET_MONTHLY_FEE');
if REG.IS_VALID(p_reg_id) then
select nvl(monthly_fee,0)
into l_monthly_fee
from registrations
where REG_ID = p_reg_id;
else
LG.POP_ERR('Invalid Registration ID: '||p_reg_id);
RETURN SYS_CODE.C_INT_NOT_DEFINED;
end if;
LG.W ('D', 'Return Reg Fee: '||l_monthly_fee);
LG.POP;
RETURN l_monthly_fee;
END GET_MONTHLY_FEE;
