Hi all, I agree with W. : NPE should be the default, and "null" cases behaviour should be planned by programmers. But I am not sure about using a new operator in rules (and do the update in Guvnor ...). Why not using some drools annotations on the getter specifying the behaviour of an eval on a null value returned by this getter ? And may be these annotation could be added to an existing POJO via the declared type syntax (just like event role in fusion) ?
Vincent.
