Event cannot start after it finishes about angular-bootstrap-calendar HOT 4 CLOSED

@Ederagp I'm following up here because you mentioned this issue on Gitter and I'd like to help if I can. I am not a maintainer of this project, but I follow the channel because I used it once-upon-a-time and like to use the understanding I gained of the project be using it to help others.

I think the warning is pretty explanatory. Events can't end before they start. In the case of this library, it uses the start and end to position elements on the calendar view, and if they end before they start, it probably ends up with negative height calculations.

You ask, Why not change the start and end date if they're wrong?

As a library author myself, I wouldn't change people's input values either. It leads to bugs that are hard to track down because the library is handling your mistake by fixing it, instead of showing you that you made a mistake. In angular, if you mutate the input value and it is being watched, it can also lead to unwanted extra digest cycles which hurt performance. If the library changed them, and then you changed them back for some reason, it could even end up as an infinite digest loop.

Your best course of action would be to correct your code so that events do not end before they start. This is not a bug.

@nbering Thank you for helping.

How could you know that an event does not end before you start?
in the plunker example the events are correct and I can not visualize the detail

This warning from your plunker example shows that the event starts at 9am and ends at 1am of the same date. The end time is 8 hours before the start time.

Great, I've modified the time format and it works perfect.

thank you very much @nbering
