At the 7:50 mark in the video where the private variable "topic" of type Topic is added to the Course class, I am not offered the choice of adding the Getters & Setters for Topic and am told "Topic cannot be resolved to a type". I am offered a variety of fixes such as Import Topic, creating a Class/Interface/Enum of Topic, down to Fix Project Setup. I do not believe I have missed any steps. Any advice? Import Topic sounds correct but I'm hesitant to continue as I don't want to deviate from the tutorial.

Time Mark 05:20. Unused URL components can be an error source. So would not it be better to write "/courses/{id}" instead of "/topics/{topicId}/courses/{id}", at the RequestMapping of the function getCourse, if the topicId is not necessary for the backend function call?

If you set the cascade parameter of the @ManyToOne annotation to 'CascadeType.ALL' or 'CascadeType.MERGE', then there will be adverse side-effects (i.e. the Topic will be overwritten).
