Team,
I'm sure this has been solved before - repeatedly, but I can't seem to find
what I'm looking for.
I'm using Stripes 1.5 with Apache Cayenne 3.0M6.
Creation of new object is a snap, I can simply pass the object to Stripes
and it does a perfect job populating the fields so that Cayenne can persist.
My issue is with Updating existing data.
I'm attempting (unless there is a better pattern) to reuse the same Bean
with a different event for "modify". The link is generated with an:
<s:link beanclass="fooBean" event="modify"><s:param name="user.pkId"
value="${fooId}"/></s:link>
The end results looks correct.
My first question is: When and Where should I "populate/inflate" the object
to be edited? I think I've simply confused myself by reading a little too
much and mixing patterns of others...
I've tried using inflating the object using a @Before annotation:
@Before(stages = { LifecycleStage.BindingAndValidation })
public void fillData()
{
// time to inflate the object for the user
}
BUT -- at that stage (err - I think) I don't seem to have the anything from
the request? I would expect (and be wrong) that my user object would be
empty EXCEPT for the pkId attribute. The entire object is empty...
Interesting enough if I get the parameter from the request directly it
works, but this seems so hacky:
int thisPkId = getUser().getPkId(); // does not work!
String strUid = getContext().getRequest().getParameter("user.pkId"); // this
works...
So - let me cut to the chase..
What is "A" recommend pattern to inflate an object based on a parameter
passed in? If I attempt to re-load the object before I call "update" I
overwrite the request params...
Thanks all!
The "ID" parameter in Cayenne is
