DonePipe cannot be use when() together

[Johnny Sung]

Here is the scenario in pseudo code with my case.

private Promise<ObjectA, Exception, Double> grabObjectAandFilter() {
    return grabObjectA().then(new DoneFilter<ArrayList<ObjectA>, ObjectA>() {
        @Override
        public ObjectA filterDone(ArrayList<ObjectA> result) {
            // Do some filter
            return getFilteredOne();
        }
    });
}

private Promise<ArrayList<ObjectB>, OneReject<Object>, MasterProgress> grabB1andB2ThenMerge() {
    return dm.when(grabObjectB1(), grabObjectB2()
    ).then(new DoneFilter<MultipleResults2<ArrayList<ObjectB>, ArrayList<ObjectB>>, ArrayList<ObjectB>>() {
        @Override
        public ArrayList<ObjectB> filterDone(MultipleResults2<ArrayList<ObjectB>, ArrayList<ObjectB>> result) {
            ArrayList<ObjectB> list = new ArrayList<>();
            list.addAll(result.getFirst().getResult());
            list.addAll(result.getSecond().getResult());
            // Do some filter
            return list;
        }
    });
}

So here is my try.

grabObjectAandFilter().then(new DonePipe<ObjectA, ArrayList<ObjectB>, OneReject<Object>, MasterProgress>() {
    @Override
    public Promise<ArrayList<ObjectB>, OneReject<Object>, MasterProgress> pipeDone(ObjectA result) {
        return grabB1andB2ThenMerge();
    }
});

I got this error
