[jboss-jira] [JBoss JIRA] (DROOLS-746) Window operators - Type safety

Window operators - Type safety ------------------------------ Key: DROOLS-746 URL: https://issues.jboss.org/browse/DROOLS-746 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.2.0.Final Environment: OS: Mac OS Yosemite 10.10.2 Java: 1.7.0_75 / 1.8.0_25 Reporter: Wilson Akio Higashino 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.
