I'm using drools-5.3.0.Beta1. I've following rule definition:

import java.util.*;

declare Student

   name : String @key

   subjectGradeMap : HashMap   

end

 

rule "Subject grade points"

dialect "mvel"

when

   $u : Student()

then

   $u.subjectGradeMap["CompSc"] += 100;

   System.out.println("Marks added");

end

While executing RHS of above rule, fireAllRules() doesn't return, it hangs.

Please help.

Thanks,

Neel
