Subject [jira] [Closed] (TAP5-1899) Tapestry BeanEditor should follow Persistence @Embedded
Date Mon, 22 Aug 2016 06:48:22 GMT

     [ https://issues.apache.org/jira/browse/TAP5-1899?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jochen Kemnade closed TAP5-1899.
--------------------------------
    Resolution: Incomplete

We assume this is no longer relevant and therefore close it.
If you still have this issue in a recent Tapestry version (such as 5.4.1 or newer), feel free
to provide the necessary information and reopen.

>             Project: Tapestry 5
>          Issue Type: Improvement
>          Components: quickstart, tapestry-hibernate, tapestry-jpa
>    Affects Versions: 5.3.2

>            Priority: Minor

> Quick Intro:  
> http://tapestry.1045711.n5.nabble.com/hibernate-Embedded-td2435807.html
> If an entity has an embedded entity which in turn has an embedded entity and so on...hibernate
is able to generate a database table for the highest level entity using the properties of
embedded entities.  The corresponding create page in T5 should simply be, <t:beaneditform
object="highestLevelEntity"/>  and the list page should simply be <t:grid source="highestLevelEntities"/>.
 
> Right now the embedded entities do not showing up unless 
> 1) bean model is customized for rendering the embedded entities.  This means T5 gets
in the way and adds a parallel interpretation to whatever hibernate is doing per JPA
> 2) the highest level entity features getters and setters to wrap the embedded entities

> 3) use Struts style dot notation to directly address embedded entities
> All of these approaches violate "Code Less, Deliver More".  And this can be solved by
using the principle "Follow Hibernate".  Just read directly from the database just Hibernate
successfully created and then used the @Embedded hierarchy to build the object model.  
> There may be a case for arbitrary embdedded properties to be exposed only through bean
model to the presentation layer...but for something being processed just fine by persistence
layer, T5 should facilitate it as well.  
> Lastly, this would really help quickstart a real world application.  Otherwise T5 just
replaces a whole lot of coding elsewhere.
