DMN13 — Wrong example in chapter "10.3.1.5"

  • Summary:

    The specification in chapter "10.3.1.5 Contexts, Lists, Qualified Names, and Context Lists"

    presents the following example:

    [{a: [{b: 1}, {b: [2.1, 2.2]}]}, {a: [{b: 3}, {b: 4}, {b: 5}]}].a.b =
[[{b: 1}, {b: [2.1, 2.2]}], [{b: 3}, {b: 4}, {b: 5}]].b =
[[1, [2.1, 2.1]],[ 3, 4, 5]]

    However line 2 is wrong since DMNv1.2 dropped the equivalence that 

    a=[a]

    therefore line 2 is problematic:

    [[{b: 1}, {b: [2.1, 2.2]}], [{b: 3}, {b: 4}, {b: 5}]].b =
 ^ b property is not available here

    as at the cursor position is not a context but two items of the root list.

    It is proposed to replace the example as follows:

    [{a: {b: 1}}, {a: {b: [2.1, 2.2]}}, {a: {b: 3}}, {a: {b: 4}}, {a: {b: 5}}].a.b =
[{b: 1}, {b: [2.1, 2.2]}, {b: 3}, {b: 4}, {b: 5}].b =
[1, [2.1, 2.1], 3, 4, 5]
