Sebastien,
Have you tested your ActionBean directly without using Mock / Test
framework? I'm going to guess that it won't work there either.
Because ORM's have the notion of persistence context... if you load an
object in one transaction and later try to persist it the object in
another transaction the object is considered detached and needs to be
re-attached to a persistence context... say for example using merge vs.
persist.
In any event, if you google your error you should find lots of
information on this topic.
This is a common issue for update or delete w/ JPA and / or Hibernate.

Hi All,
I've started a new simple project using stripes and stripersist/hibernate.
As the basic development is finished I wanted to add some testing.
Folowing the example given in
http://www.stripesframework.org/display/stripes/Unit+Testing I've used
MockServletContext.
I want to test my UserActionBean. This class has simple handler method
such as list(), view(), cancel(), create(), edit(), save(), delete()
and update();
I also have a getter and setter for the User entity.
The update() method handler is as simple as:
public Resolution update() {
getDao().save(getUser());
getDao().commit();
return new RedirectResolution(this.getClass(),
"view").addParameter("user", getUser());
}
The delete() method handler:
public Resolution delete() {
getDao().delete(getUser ());
getDao().commit();
return new RedirectResolution(this.getClass());
}
I've writen a test class UserActionBeanTest and all test run correctly
(list, view, create, save ...) but the update and delete one.
@Test
public void testDelete() throws Exception {
User user = createUser();
MockRoundtrip mockRoundtrip = new MockRoundtrip(getServletContext(),
UserActionBean.class);
mockRoundtrip.addParameter("user", String.valueOf(user.getId()));
mockRoundtrip.execute("delete");
String redirectUrl = (new
RedirectResolution(UserActionBean.class)).getUrl(Locale.getDefault());
verifyDestination(mockRoundtrip, redirectUrl);
}
@Test
public void testUpdate() throws Exception {
User user = createUser();
MockRoundtrip mockRoundtrip = new MockRoundtrip(getServletContext(),
UserActionBean.class);
mockRoundtrip.addParameter("user", String.valueOf(user.getId()));
mockRoundtrip.addParameter("user.name", "newName");
mockRoundtrip.execute("update");
RedirectResolution redirectResolution = new
RedirectResolution(UserActionBean.class, "view").addParameter("user",
user);
String redirectUrl = redirectResolution.getUrl(Locale.getDefault());
verifyDestination(mockRoundtrip, redirectUrl);
assertUserUpdated(user);
}
When I run them I received some error message saying that the object
user is detached.

I really can't work out what's wrong and why the object is detached
when using MockServletContext.
If any one could help it would be much appreciated.
Don't hesitate to ask if you need more info.
Thanks.
