> It seems the rule compiler is not correctly checking type safety when using window operators to define rule conditions.
> I defined a rule using the following code (note that I incorrectly used "time:window" to define the window, instead of "window:time"):
> declare SensorReading
>     @role(event)
>     @timestamp(timestamp)
> end
> rule "boilers"
>     when
>         $b1: (SensorReading(sensorId == 1L && status == SensorStatus.ON) over time:window(10s)) 
>     then
>          ....
> end
> The rule has been compiled and executed, but not following the correct window semantics.  The forum link contains a full description of the (unexpected) behaviour I found when defining rule like this.
