[rules-users] Validation in Guvnor fails due to unrecognized method of implemented interface

Hi, I have a class which implementes several interfaces class MyClass implements interA, interB, interC { private String nameA; private String nameB; private String ownString; public String getNameA(){ ---impl of method from interface interA return nameA; } public String getNameB(){ ---- impl method from interface interB return nameB; } public String getOwnString{ ---- own method return ownString; } } Another class, MyBiggerClass has MyClass as its attribute: class MyBiggerClass { private MyClass myClass; public MyClass getMyClass(){ return myClass; } } In a rule, I use MyBiggerClass as follows: $mybig : MyBiggerClass() eval($mybig.getMyClass().getNameB().equals("HelloWorld")) The evaluation fails, and it said unable to resolve method using strict-mode: interA.getNameB() As you can see, the validator checks as if the getNameB was a method of interA (the first interface). I'm wondering whether this is a bug, or do I have to somehow change the structure of my class. But the question is, why does it check the interfaces not the class itself?
