[rules-users] memberOf in a eval statement (dialect mvel)

[Edson Tirelli]

   Not sure why do you want to do that. Better would be to simply:

rule "Your 5 Rule"
        dialect "mvel"
        when
                 $l:ArrayList( this contains "test" )
        then
                #actions
                System.out.println("OK");
end

   If you want to do that inside an eval, MVEL does not have "memberOf"
operator, but it has "contains", so just write:

eval( $l contains "test" )
