Comment 3 for bug 794290

Definitely not related to the js, because all the generation happens from python.

It is very likely solvable inside the view, (and without touching of the presenters) - the current code makes sure that one event is only added once, this is what needs to change according to this ticket.

A usability point. I understand that displaying the all day events multiple times in the day view, in case they are visible in multiple layers, is good for the users. However, what should happen with the non-all-day (single) events? Would it be not disturbing if the same event is shown multiple times in a given timeslot of the day view, in case it's part of multiple layers?

Also: in the week and month views, would it be not disturbing to show the same event multiple times? (because of space)

If the multiplicity of an event displayed is conditional and depends on the view (day, week or month), or, if it depends on the event type (all-day or single), then the implementation will be more complex. If the multiplicity is unconditional, then it's simpler to implement this change. All in all: this change involves a policy decision because of possible, yet unthought side effects.
