Traceability matrix: LO with the list of BOs leaves line empty

[danopolan]

When the mapping of traceability matrix is one Learning Objective (LO) to more Business Objectives (BO), there is an empty line in the generated table instead of two X marks.

Tested on istqb_product_base and istqb-ctal-ta@release-version repositories.

@Witiko When can I expect a fix?

@mhamburg it was promised on Friday, so today :)

Today's Thurstday. I have the fix planned for Friday, i.e. for tomorrow.

I can reproduce the issue with the example document from this repository.

For example, here is the file example-document/traceability-matrix.yml:

traceability-matrix:
  2.1.1: 1
  2.1.2: 2
  2.1.3: [2, 3]
  2.2.1: [3, 4]
  2.2.2: [3, 4, 5]
  2.3.1: [4, 5, 6]

Here is the second page of Appendix B from the produced document example-document.pdf:

As you can see, all rows are empty except those for the learning objectives 2.1.1 and 2.1.2.

According to the screenshots in #61, the template produced the correct output when the initial support for traceability matrices was added in #90 on Aug 21, 2024. Bisecting the artifacts from branch main shows that the template produced the correct output until and including commit 03180ab from Nov 25, 2024:

However, after commits 648e95d..eba4323, the template started producing the current output:

In these commits, we switched from using our own version of the library lua-tinyyaml to the distribution version. However, the distribution version is outdated and parses numbers nested in sequences as strings. For example, the distribution version parses the file example-document/traceability-matrix.yml as follows:

traceability-matrix:
  2.1.1: 1
  2.1.2: 2
  2.1.3: ["2", "3"]
  2.2.1: ["3", "4"]
  2.2.2: ["3", "4", "5"]
  2.3.1: ["4", "5", "6"]

Since our code is type-safe, this causes our template not to "see" the nested numbers.

Therefore, in commit 02ee782 from PR #175, I started downloading the current version of the library in our Docker image, which fixes the issue:

In Witiko/markdown#218 (comment), I also contacted the maintainer of the distribution version to update it. After it has been updated, we can revert the changes from commit 02ee782 and go back to using the distribution version of the library.

@mhamburg I reran the CI for branch istqb-ctal-ta@release-version. The traceability matrix in Appendix B of the produced file ISTQB-CTAL-TA-Syllabus-v4.0-EN.pdf seems fixed:
