Stripes: I can pre-populate a form, but after submit the formBean is null - stripes

Question

I can pre-populate my Stripes JSP form with an object, client in my case, but when I submit this form, my object is returning as null.
I have created a second "temp" object that is a parallel duplicate of client and this retains its values, so I can't see an issue passing an object in the request
My form is as follows :
<s:form beanclass="com.jameselsey.salestracker.action.ViewClientAction">
<s:hidden name="clientA" value="${actionBean.clientA}"/>
<s:hidden name="clientId" value="${actionBean.clientId}"/>
<table>
<tr>
<td>Name : </td>
<td><s:text name="client.name"/></td>
</tr>
<tr>
<td>Sector : </td>
<td><s:text name="client.sector"/></td>
</tr>
<!-- omitted some attirbutes, not needed here -->
</table>
</s:form>
My action looks like
public class ViewClientAction extends BaseAction
{
#SpringBean
ClientService clientService;// = new ClientService();
private Integer clientId;
private Client client;
private Client clientA;
public void setClient(Client client)
{
this.client = client;
}
public Integer getClientId()
{
return clientId;
}
public void setClientId(Integer clientId)
{
this.clientId = clientId;
}
public Client getClientA()
{
return clientA;
}
public void setClientA(Client clientA)
{
this.clientA = clientA;
}
public Client getClient()
{
return client;
}
#DefaultHandler
public Resolution quickView()
{
clientA = clientService.getClientById(clientId);
client = clientService.getClientById(clientId);
return new ForwardResolution("/jsp/viewClientQuickView.jsp");
}
public Resolution save()
{
clientService.persistClient(client);
return new ForwardResolution("/jsp/reports.jsp");
}
public Resolution viewClientInfo()
{
client = clientService.getClientById(clientId);
return new ForwardResolution("/jsp/viewClientClientInfo.jsp");
}
...
If I set a breakpoint at clientService.persistClient(client); I can see that ClientA has all of the original values of the object, yet client is nulled.
Have I missed something that binds the form bean to the client object in my action?
Thanks

Answer 1

Add this line in your JSP:
<s:hidden name="client" value="${actionBean.client}"/>

Answer 2

I got this scenario working by adding a #Before method to re-hydrate the nested object. After this, save works properly
#Before(stages = LifecycleStage.BindingAndValidation)
public void rehydrate() {
if (context.getRequest().getParameter("save")!=null){
this.domainObject = getHibernateSession().load(DomainObject.class, context.getRequest().getParameter("id"));
}
}
public void save(){
Session session=getHibernateSession();
session.update(domainObject);
session.commit();
//...
}
