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...
