Julian Klein updated JBRULES-3622:
----------------------------------
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:
{code}
$encD : TimeBoxedFact(yearRecorded == durationCycleYear )
$encN : TimeBoxedFact( ID != $encD.ID, datetimeRecorded overlappedby[1ms,90d] $encD.datetimeRecorded )
{code}
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:
{code}
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());
}
}
{code}
The stack trace is as follows:
