I don't think I'm even close to writing idiomatic Tapestry 5 (if such a
thing even exists), but here is the pattern I've been using:
EditMyBean.java
-------
public class EditMyBean {
@ApplicationState
private MyDBClass _theBean;
public MyDBClass getTheBean(){return _theBean;}
public void onActivate(long id){
_theBean = getDAO().getById(id);
}
public long onPassivate(){
return _theBean.getId();
}
@Component(id = "beanEditForm")
private BeanEditForm _beanEditForm;
public void onValidate(){
//Validate the changes. Add errors to the form using
//_beanEditForm.recordError(String). This will automagically
//cause the page to redisplay.
}
public void onSuccess(){
getDAO().saveOrUpdate(_theBean);
}
}

EditMyBean.html
-------
<html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<head><title>EditMyBean</title></head>
<body>
<t:beaneditform object="theBean">
<t:parameter name="id">
<!-- Marking the getter or setter with @Nonvisual is far
- preferable, but this will do in a pinch.
-->
</t:parameter>
</t:beaneditform>
</body>
</html>
