The general concept: I am creating a newspaper website which articles (created from a Seblod form) and newspaper issues (for the moment Categories created using Seblod form). I want the following: When a user creates an article, he assigns it an issue (April 2016 for example). The article stays hidden until the editor-in-chief publishes the issue at which point every article in that issue goes published.
How I implemented it: I used categories as issues. I didn't manage to create such workflow with simple state variables or other article-like content.
My question: How do I only list articles whose category is published on the website?
OR: How do I implement such a workflow differently?
