[rules-users] accumulate min over java.util.Date

Should I be able to do an accumulate min over java.util.Date objects? Like this: $minDate : Date() from accumulate(MyFact ($startDate : startDate), min($startDate)) I would have thought so, but when I try it, I'm getting: Caused by: java.lang.ClassCastException: java.util.Date cannot be cast to java.lang.Number at org.drools.base.accumulators.MinAccumulateFunction.accumulate(MinAccumulateFunction.java:76) If it should work, then it's possible I'm doing something else wrong, but everything looks correct to me. I can always work around it by getting the milliseconds from the Date object and doing the min over that... it's just not as clean looking. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/accumulate-min-over-j...
