Description
When trying to determine if two dates overlap using the "overlappedby" keyword with parameters in a rule, Drools throws a ClassCastException. If I use another temporal keyword such as "coincides" with parameters, the rule works as expected. I am using a StatefulKnowledgeSession and this occurs after I insert facts into the session. The facts I insert are of a different type than TimeBoxedFact. The LHS is as follows:
$encD : TimeBoxedFact(yearRecorded == durationCycleYear )
$encN : TimeBoxedFact( ID != $encD.ID, datetimeRecorded overlappedby[1ms,90d] $encD.datetimeRecorded )
durationCycleYear is a global Integer equal to the four digit year (e.g. 2012 or 1998; declared as follows "global Integer durationCycleYear;")
Here is what the TimeBoxedFact object looks like:
package com.company; import java.io.Serializable; import java.sql.Timestamp; public class TimeBoxedFact implements Serializable{ protected Timestamp datetime = null; protected int ID; private static final long serialVersionUID = -7640003804511140444L; public int getID() { return this.ID; } public void setID(int id) { this.ID = id; } public Timestamp getDatetimeRecorded() { return this.datetime; } public java.util.Date getDateRecorded(){ return new java.util.Date(this.datetime.getTime()); } public int getYearRecorded(){ return calendarDateRecorded.get(Calendar.YEAR); } public void setDatetimeRecorded(Timestamp dt) { this.datetime = dt; //create the calendar object calendarDateRecorded = Calendar.getInstance(); calendarDateRecorded.setTimeInMillis(datetime.getTime()); } }
The stack trace is as follows:
java.lang.ClassCastException: org.drools.common.DefaultFactHandle cannot be cast to com.company.TimeBoxedFact
