Generating User_id using SYS_GUID()

Question

Hi,
I am using JDev 11g Release2. I have created a trigger using the following sql script.
create or replace TRIGGER trig1
BEFORE INSERT
ON user1
FOR EACH ROW
DECLARE
v_user_id VARCHAR2(64) := NULL;
BEGIN
IF :NEW.user_id IS NULL
THEN
SELECT sys_guid() INTO v_user_id FROM DUAL;
:NEW.user_id := v_user_id;
END IF;
END;
This trigger is working fine when I am trying to perform an insert operation on the database level. However, when I am trying to insert through the form(View object), it is asking for the id to be entered manually.
Can anyone help me with this?
Thanks & Regards,
Suganya.

Thanks Jabr,
But in my case i have one VO named UserUserProfileVO which contains both UserEO and UserProfileEO.When i try to create the new user information through that UserUserProfileVO it is throwing the following exception
(oracle.jbo.DMLConstraintException) JBO-26048: Constraint "USER_PROFILE_FK1" is violated during post operation "Insert" using SQL statement "BEGIN INSERT INTO USER_PROFILE(USER_PROFILE_ID,USER_ID,FIRST_NAME,LAST_NAME) VALUES (:1,:2,:3,:4,:5) RETURNING USER_ID INTO :6; END;".
