Some events from IPhoto do not show up in Itunes

I just imported a set of photos in IPhot0 as a new event. However, when I tried to sync my Ipads (Ipad 1 and Ipad 3) this new event doesn't show up. This happened after the last upgrade of IPhoto (version 9.4.2). I have removed the IPod Photo Cash and rebuild it by a new sync, but that didn;t help either. The last event is not visable in the Photo tab in Itunes. Also the recent album has zero photo's.

Anyone with help?
