[rules-users] Using memberOf on inline mvel list was Re: Welcome to the "rules-users" mailing list
Apologies for the initial subject. Changing to a more appropriate one.

I want to create a rule that will match when Age is greater than 20 and name is one of
“Fred”, “Barney”, or “Wilma”. These entries are stored in the Map props, so that to get
age, you would call person.getProps().get(“AGE”)
rule "My Rule"
dialect "mvel"
when
$person : Person(
props[“AGE”] > 20,
props[“NAME”] memberOf [“Fred”, “Wilma”, “Barney”]
)
then
System.out.println("found match”+$person);
End
But I am running into a parsing error:
no viable alternative at input ')' in rule "My Rule" in pattern
Person.
The second condition seems to be the problem. Can I check for membership inside a List I
create inline in mvel?
