I've got an expression that returns all "incidents" that matches the area of responsibility for a "user".
Is there a way to programatically invert such an expression to return all "user" who are responsible for an "incident"? The problem with a manual conversion is that it introduces the changes of bugs creeping in. A trivial example: exp=ExpressionFactory.matchExp(Incident.TO_USER, user) => all incidents assigned to a user. exp=ExpressionFactory.matchExp(User.TO_INCIDENT, incident) => all users assigned to an incident. A more complicated example by throwing in roles: exp=exp.orExp(ExpressionFactory.matchExp(Incident.TO_ROLE + "+." + Role.TO_MEMBER_ARRAY + "." + Member.TO_USER, user)) => return all incidents where a user is the member of the role who's responsible. The trick here is that the role is optional, so an outer join is used. I need the reverse query that returns all the users responsible for an incident... -- Øyvind Harboe Embedded software and hardware consulting services http://consulting.zylin.com
