Error when attaching value set to Extra information type in HR

Hi,

We created a new value set with a special validation rule containing the following Validate event, containing the following code:

FND PLSQL "declare

l_value varchar2( 20 ) := :!value ;

l_valid NUMBER := 0 ;

BEGIN

select INSTR(l_value ,'@')

into l_valid

from dual;

IF (l_valid=0) THEN

fnd_message.raise_error ;

END IF ;

END;

"

When attached to the flexfield and save the record we receive the fllowing error:

Error message is : APP-FND-00952: The flexfield on this field contains a value set ([]) that uses special or pair user-exit validation. This prohibits operation in the mode that optimizes performance over a wide area network.
