[rules-users] Can't check if an attribute is member of an object of class class com.sample.WorkDays

[Marcin Krol]

I'm doing this:

ThermostatTimeData ttd1 = new ThermostatTimeData("January", "Monday", 14);
session.insert(ttd1);
WorkDays wd = new WorkDays();
session.insert(wd);
session.fireAllRules();
printoutThermostatData(ttd1);

and then this:

rule "Rule 1"
  when
     $wd : com.sample.WorkDays()
     $ttd : ThermostatTimeData ( day memberOf $wd )
  then
	modify ( $ttd ) {
	 setDaytype("workday")
	}
	System.out.println("Rule 1 fired.");
end

And I get the error like in subject. Anybody knows why?


WorkDays.java:

package com.sample;
import java.util.ArrayList;
import java.util.List;


public class WorkDays {
		private List<String> wd;
		
		public WorkDays() {
			this.wd = new ArrayList<String>();
			this.wd.add("Monday");
			this.wd.add("Tuesday");
			this.wd.add("Wednesday");
			this.wd.add("Thursday");			
			this.wd.add("Friday");			
		}
		
		public List<String> getWorkDays() {
			return this.wd;
		}
}
