What would these FEEL expressions evaluate to?

> { a: 10, b: a + 10 }
> { b: a + 10, a: 12 }

I would want results per DMN 1.1. If it is by later version of spec please specify.

Hi @deostroll ,

The first would be {a: 10, b:20}, the second would be {b: null, a:12}.

As context entries are evaluated, they are available in scope for subsequent entries. For the second one, the a is not in scope so therefore would be null. Adding 10 to null is null.

I'm not sure if that was for 1.1 or not (I came to DMN after 1.1), but that is what it is now.

You'll find some tests here: https://github.com/dmn-tck/tck/tree/master/TestCases/compliance-level-3/0057-feel-context.

I concur with @StrayAlien , to be even more precise, the second one would be {b: null, a:12} and an error.

DMNv1.1 onwards specify:

An expression in a context entry (...) may reference keys (as QNs) from other context entries in the same context. These references SHALL be acyclic and form a partial order. The expressions in a context SHALL be evaluated consistent with this partial order.
