>             Project: Tapestry 5
>          Issue Type: Bug
>          Components: tapestry-core

> Here is a simple example: 
> public interface HasName {
> 	String getName();
> }
> public abstract class AbstractBean implements HasName {
> }
> public class TestPage {
> 	@Property
> 	private AbstractBean bean;
> 	public void onActivate() {
> 		bean = new AbstractBean() {
> 			public void setName(String name) {
> 			}
> 		};
> 	}
> }
> TestPage.tml
> ...
> 	<h1>${bean.name}</h1>
> ...
> Error message is:
> Exception assembling root component of page manager/tools/TestPage: Could not convert 'bean.name' into a component parameter binding: Class smarter.ecommerce.smeco.manager.pages.tools.AbstractBean does not contain a property named 'name' (within property expression 'bean.name'). Available properties: class, componentResources.
> Everything works fine if I change the bean class to:
> public abstract class AbstractBean implements HasName {
>   public abstract String getName();
> }
