> To add an artificial column to Grid one have to do a lot of work. Tapestry could be smarter by creation of BeanModel. 
> A parameter whose name could not be matched to an existing  property should be added automatically.
> <t:grid source="users" row="user" model="model">
>         <t:parameter name="deleteCell">.....</t:parameter>
> </t:grid>
> public class Start {
>     ...
>     @Inject
>     private BeanModelSource beanModelSource;
>     
>     @Inject
>     private ComponentResources resources;
>     
>     public BeanModel getModel() {
>         BeanModel model = beanModelSource.create(User.class, false, resources);
>         model.add("delete", null);
>         return model;
>     }
> }
> In this case the following class can be reduced to:
> public class Start {
> }
