[rules-users] Example code to test an object that contains a collection of other objects?

Hi, I have read around for an entire day but still can not figure out how to write the following in DRL syntax: "When a person has a an advanced degree, print 'person is educated'" A person has many degrees. So, I have a Person POJO and a Degree POJO. A Person object has a field callled "degrees", which is nothing more than an ArrayList<Degree>. A degree has nothing but a name field, which is a String. In regular java, it would be: for (Degree d : person.getDegrees() { if (d == "phd" || d == "ms" || d == "jd" || d == "md") { System.out.println("person is highly educated"); } } I can not do this in the Guvnor either. I've tried using a contains keyword but I just can't my rule to fire. Simple rules otherwise fire just fine ,so my plumbing is all wired up correctly. -- View this message in context: http://drools.46999.n3.nabble.com/Example-code-to-test-an-object-that-con...
