This is intriguing has a time, I use in the project the schedule of the primefaces to add events, so long, all the computers add and send to the online database, there is also a method that lists all the details of each event when you click on it, only some computers are sure to see events registered by one but on another PC is not possible, I have no idea why this is happening or how to solve.
I created this on my PC and I can see it. ThiswascreatedonanotherPCandIcanstillsee(frommypc). ThisonewascreatedinanotherPCandIcannotsee(butstillanotherPCwithoutbeingwhatIcanseetheevents,canshowthoseones.)
So maybe it was confusing, I think the events are showing up in pairs (I do not know if they really are even) but I know the 4 that I tested 2 can see the details of their events and the others do not.
Detail all events appear in the scheuld for all PCs but the details do not.
