Yes, typically you make a field persistent and then bind the parameter to the persisted field.

> If you use @Persist on on Component property the value is kept between 2 request, but not when submitting a Form for instance.
> I think it would be very useful / powerful -particularly with Hibernate- to give access to the Persisted value even when a when a Form is submitted (if it is possible...)
> Ex :
> 1 - Get my instance of a User from Hibernate and display it with the BeanEditForm and use @Persist on it
> 2 - Update my values and post the form
> 3 - My instance of user would be directly update (because the BeanEditForm would use the persisted value and not a freshly created one)
> 4 - use onSuccess to do a Merge and a Commit :)
> Code exemple :
> public class UserEditor {
> 	@Parameter(required=true)
> 	@Property
> 	@Persist
> 	private User _user;
> 	
> 	@Inject
> 	private UserManager _userManager;
> 	
> 	protected void onSuccess() {
> 		//Save the Profile Update
> 		_userManager.merge(_user);
> 		_userManager.commit();
> 	}
> }
> Associated template
> <t:beanEditForm t:object="user" xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd" />
