             Summary: strict mode evaluation taking interface instead of class
                 Key: JBRULES-3392
                 URL: https://issues.jboss.org/browse/JBRULES-3392
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-compiler (expert)
    Affects Versions: 5.3.1.Final
         Environment: java 1.6.0_29 on windows 7
            Reporter: Lubos Pechac
            Assignee: Mark Proctor


I am getting a compilation error with my drl, that worked in 5.0.1:

Unable to Analyse Expression las.id == $las.id:
[Error: unable to resolve method using strict-mode: piag.entityinterface.ILink.id()]
[Near : {... las.id == $las.id ....}]
                 ^
[Line: 42, Column: 30] : [Rule name='rule1']


here's the rule:
rule "rule1"
when
  $las : Link(name == "GA1")
  $pi : PayItem(las.id == $las.id, amount > 0, comparisonType == "ECHT")
then ...


interface ILink is empty:
public interface ILink { }

class Link extends ILink adds a few attributes including id, name, amount, comparisonType...

interface IPayItem has this getter:
public ILink getLas();

class PayItem overrides this getter:
@Override
public Link getLas() {
  return this.las;
}


It seems like drools is incorrectly treating $pi as IPayItem. IPayItem.getLas() returns ILink which does not have method id(), as the message says. But PayItem.getLas() returns Link which does have attribute id.
I didn't specify anywhere that $pi is IPayItem so why does it do this?
