strict mode evaluation taking interface instead of class

    Details

      Description

      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?
