I have a mac mini with OSX 10.10.4 and Server 4.1.3 with an activated calendar service. Basically it works perfectly. Yesterday i tried the function "Locations and Resources". I created 2 locations "Living room","kitchen" and 2 resources "Playstation", "Oven". Then i created a new event on my iMac (OSX 10.10.4) and on my MacBook (OSX 10.10.4) with the new created locations and resources and it works perfect. After that, i tried it on a iPad (iOS 8.4). I created an new event. I could select a location perfectly (with intellisense) but i could NOT select a resource (no intellisense....). So I typed the name of the resource "Playstation" by Hand. If i try to save to event i got the errormessage "'' is not a valid e-Mail address". Please help me, because i dont know whats the problem. ps: sorry for my bad englisch. many greetix from austria.
