Description Edgar Mueller CLA 2012-01-19 09:49:12 EST 
The ObserverBus in its current state does not enable it to aggregate values from multiple observers.  Instead, the first observer found that returns a value is used.  The return values of the remaining observers will be discarded.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

Closing this since no activity happened and it is in fact possible to get a list of all results, although this may seem a bit ugly:

A proxy = getObserverBus().notify(A.class);
List<Result> callResults = ((ObserverCall) proxy).getObserverCallResults();
