Thanks for your interest in that problem. I think my situation is quite
current. It applies in the case when you want to display the number of
elements in master object in a master/details situation.
The solution of Matthew seem to me quite conveniant except for the fact
that I'm not quite sure how to get an IObservableMap from that example
instead of an IObservableValue.
Required by your solution:
IObservableValue listSize = new
NotifyingListSizeProperty().observe(eList);
Required in my situation
IObservableMap[] map = new IObservableMap[3];
..
IEMFValueProperty prop =
EMFProperties.value(DairyStudioQualityPackage.Literals.SAMPLE_SET__SAMPLES);
??? map[2] = new NotifyingListSizeProperty().observe(prop); ???
