Yes, that's what I meant. If you don't do it, you try to persist objects
that are in an inconsistent state, which could easily explain the DELETEs.
Now why this causes an infinite recursion, I have no idea. Sorry.

PS: You are not locking the Role objects, so I assume you left the
"useImplicitLocks" parameter at its default of "true" in OJB.properties?

u mean i should code as such?
public static User createUser(){
User user = new User();
user.setLabel("yenonn");
user.setDesignation("programmer");
user.setFullName("Hiu Yen Onn");
user.setPassword("yenonn");
for(int i=0; i<3; i++){
Role role = new Role();
role.setLabel("role"+i);
role.setRoleName("syl-admin");
role.setAllowCreate(1);
role.setAllowDelete(1);
role.setAllowEdit(1);
role.setAllowSearch(1);
role.addUser(user);
user.addRole(role);
}
return user;
}
but, it yields more errors in the log file... it keeps looping, and
updating
the records, until it is aborted and rollbacked

Does user.addRole(role) call role.addUser(this)? If not maybe that's
something to try to solve your problem?
