addSubclassOperations method is introduced in the commit.
@samuel34 I remember that I did comment out the call to that method because it seems to only handle the POST operation. Unfortunately, I’m having a hard time testing it out on my machine because of some performance reasons. You may try out uncommenting the method call to see how things show up in the doc.
Maybe @pascal have insights on what needs to be improved in addSubclassOperations method.
