> Components: Streaming
> Affects Versions: 1.1.3

> Fix For: 1.2.0

>
> The ContinuousEventTimeTrigger registers a timer when elements arrive. The
> timers might be registered past the end of the window. In this case, the
> window is cleaned up and doesn't fire at all. That is certainly not what
> users have in mind when they use the custom trigger.
> I proposed to let it behave like a normal EventTimeTrigger in addition to its
> continuous firing capabilities. So it should fire at the end of the window
> regardless of timers set.
