[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;
                }
}
