IllegalStateException on an observable list (original) (raw)

This indeed was the problem. Point is; I simply used code completion on the Change class, found the getRemoved method, and used that. I figure this will be happening to a lot of people. Maybe it is user friendly to provide a small hint in the IllegalStateException's text, something like "Have you maybe forgotten to iterate over the change sets?".

it seems you've missed to iterate through the collected changes in that Change. if you wrap your for-loop in while(c.next()) it'll work. you can then optionally check if the change was caused by appointments being removed from the list or by something else. See http://docs.oracle.com/javafx/2/api/javafx/collections/ListChangeListener.Change.html for reference. Martin
