Hi Guys,

I am using DROOLS FUSION last version
It is very important for me that events arrive in the order i fire them
, this is a part of the code used for stream mode :

after this part I just start inserting Events into the ksession , i.e
ksession.insert(new Event(a)) ...

does this suffice to make the the engine in stream mode and hence ordered ?
In the example app , Events were fired as they arrive , but a timestamp
was given , and also agenda and jobs were used.
Is that necessary for the engine to work in stream mode ?
I have a piece of code that gives me different results every time I run
it ?! it is in stream mode , but for some reason the rule either do not
fire , or do not print the output. is there a way to debug into this ?

thank you .
