Hi to all. This is my first question in the forum, so if this allready been answered my apoligues!
Im creating an app that allows several staff members to schedule events on several diferent rooms (for several diferent days).
Everyone at the event (participants) will signin and schedule a room at almost the same time (lots of peolpe at the same time)
My problem is that two staff menbres can schedule the same room for the same hour and it only becomes aparent AFTER both of them syncs on save…
How can i prevent this from happening? Any workaround? Can the app check the server before save? This is a major problem since it makes the app useless!!!
Thanks in advance Jorge
