First, thank you all for the code review and the suggestions.

I guess writing a TestFactory with randomly generated numbers would make sense. But it's also not trivial, because it requires reprogramming the logic of how the events are created, to ensure it's correct.

If someone finds time to do it, it's probably worth the time. Wouldn't be surprised if there is another error in this spaghetti code.

Because this PR is now 2 Years old ... I can tell you that it's tested for that time in a huge application with thousands of users.

This PR fixes an issue when editing entries in a ListView.

I don't really plan to extend the test further, unless someone points out an error, or suggests a simple modification.
