[rules-users] if else implementation in one rule

[Wolfgang Laun]

An else in a rule doesn't make sense, because the LHS can be false for any
number of reasons, in your example:
  - no employee at all
  - an employee not in state MH

If you want this to be in a single rule you'll have to have only one action
that's executed when the LHS matches.

You know that you can code any RHS actions in a DRL function (or a Java
static or non-static method) and call these from different RHS?

But if you are hell-bent on doing it in a single rule, use a Java if
statement on the RHS.
