[rules-users] 4.x to 5.1.0 Rule migration issue

[Michael Anstis]

As an aside, if you can change the rule definitions it'd be preferable to
remove the eval:-

rule "EmailVerificationCheck"
salience 500
when
    $c : RuleContext (paymentMethod == "P_EXPRESS", trustedUser==false)
    $a : RuleAction (action == null || == "VERIFY")
then
   ...
end

isTrustedUser() is a member of RuleContext and you can therefore access it's
boolean properties like any other.

Also, you could split the RHS into different rules too:-

rule "EmailVerificationCheck #1"
salience 500
when
    $c : RuleContext (paymentMethod == "P_EXPRESS", trustedUser==false,
PEmailVerified==false)
    $a : RuleAction (action == null)
then
    modify($a) {
        setAction ("VERIFY");
    }
end

rule "EmailVerificationCheck #2"
salience 500
when
    $c : RuleContext (paymentMethod == "P_EXPRESS", trustedUser==false,
PEmailVerified==false)
    $a : RuleAction (action == "VERIFY")
then
    $a.getRuleNames().add("PEmailVerificationCheck");
    update($a);
end
