Hi Biplob,
The message you mention should not be a problem here. It just says you
can't use your events as POJOs (e.g. you can't use keyBy("chargedAccount")
).
Your code seems fine and without some example data I think it will be hard
to help you.
As for the PART 2 of your first email.
In 1.3 we introduced NOT pattern but right now it does not support time
ranges in which a pattern should not occur. The thing you can do though is
to specify a positive Pattern like: ("a" -> "b" within 1s) and select the
timeouted patterns, which in fact are the ones that you want to trigger
alerts for.
