Ruoyun Huang commented on BEAM-6354:
------------------------------------
If I understand it correctly, my input is bounded, thus maybe not relevant? My
code is like this:
final PCollectionView<Integer> view = pipeline.apply("Create47",
Create.of(47)).apply(View.asSingleton());
I was tracing down the code path based on your suggestion. I am 90% sure that
the reason for empty output is trigger not filed (evidence being, onTrigger()
function never been executed).
