Solution for drools problem 0
Solution for the problem with drools.
The after evaluator correlates two events and matches when the temporal distance from the current event to the event being correlated belongs to the distance range declared for the operator.
The temporal distance interval for the after operator is optional:
If two values are defined (like in the example below), the interval starts on the first value and finishes on the second.
If only one value is defined, the interval starts on the value and finishes on the positive infinity.
If no value is defined, it is assumed that the initial value is 1ms and the final value is the positive infinity.
solution: change "after" --> "after[0ms]"
