Error message customization issues

Question

Hi ppl,
This is with regards to the issue with customization error messages, I have already gone through the following,but haven't been able to achieve what i want:-
"Chapter 8.2-8.3" "Business Rules in ADF Business Components".( white paper )
ADF Faces: How suppress item validation on partial submit ( Frank's blog entry )
So im extremely dull or have been looking at the wrong place ( or both :( )
my jdev version :-10.1.3
My use case is follows, extremely simple form page for creating a user log in along with other information like passwords,description etc.
I have certain basic validations
-should contain one numeric
-must not be less than 8 charecters etc
i can do the following:-
make my own customized message bundle and successfully throw it when my custom method validator fails , i do so by using the command:-
throw new AdminJboException (AdminMsgBundle.USER_ID_NO_SPACE,params);
where AdminMsgBundle is my customized bundle message class and AdminJboException is a custom class that extends JBo exception ( for conveniance ).
What i can't do is this :-
my error logs:-
JBO-27024: Failed to validate a row with key null of type ........
User Id cannot contain spaces ( my validation message )
User ID - JBO-27025: Failed to validate attribute UserId with value .....
User ID - JBO-27014: Attribute UserId in AdminAppModule.UserViewObj is required
At validation ( i presume at validateEntity() ), my exception gets thrown ), but before that the JBO-27024 gets thrown (because the data doesnt get validated and hence not stored and hence null), following which the required error is thrown , following which the 27025 and 27014 are thrown. Is there anyway i can suppress the JBO default error messages ONLY when i know for sure that my validation error message has been thrown. I was able to suppress the JBO-27014 exception altogether from the EntityModelImpl ( out of frustration ) , and it worked , but obviously it hampered proper functioning in other areas.
My question is :--
Which is the simplest cleanest way of throwing only your customized message and ignoring the default JBO ones when your exception is thrown , and letting things go normally if your customized exception is not thrown... ?
P.S i can even override the "content" of the message being thrown from 27014 etc, but thats not what i want .
Thanks in advance !
