[rules-users] using global variable in LHS

[Miles, Eric]

Not necessarily, particularly since his global is a List.  You could also use it in a from clause.  Ie:

Global List someList;

Rule "my rule"
	When
		Fact(val > 45) from someList;
	Then
		System.out.println("Woo hoo I'm happy");
end

Fact ( eval ( globVar.allFine ) )

AFAIK the evals are the only way.
