> 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?
