[rules-users] Interface and @key in declare

Hello, I want to declare a new fact base on an interface, f.e.: (i leave away all those publics) interface BoInterface { int getId(); void setId(int id); } when i declare the fact declare BoFact ( bo : BoInterface @key ) the system throws an exception the a class is expected but an interface is found, when trying to perform the equals method. Is there a restriction that @key cannot be used in a declare? Greetings, Bernd -- View this message in context: http://drools.46999.n3.nabble.com/Interface-and-key-in-declare-tp3868085p...
