Change Details

Consider this (fairly typical) situation: 1. Student A decided to write a new article X and added the article to the course by clicking "Add article". The article X is rendered without a link because it does not exist yet. 2. Student B decided to expand article Y and added the article to the course by clicking "Add article". The article Y is rendered with a link because it already exists. 3. After student A creates article X, in the students table the article will continue to appear without a link (creating an impression the article hasn't been created).
