Hi, The past couple of weeks I've been trying to learn Stripes, and I have to say I really like what I'm seeing so far. I bought the book and used the website, they're both great resources and I have the feeling I am slowly getting up to speed with the basics. However, there is some information on the website that makes me scratch my head.
I looked at the best practices page and the suggestion Use @Before methods to pre-populate domain objects confuses me. The description that's underneath it, doesn't really help me either. It says: When creating screens to edit existing persistent objects it's nice to be able to avoid copying all the properties from the nested domain object to the persistent one that you just looked up from the database. If you pre-populate the object from the database, Stripes will just bind the values from the request like normal, leaving you with an updated object ready to save. Is this best practice necessary for things to work smoothly? I have an ActionBean with a form, a domain object, and a Converter that loads the domain object from a DAO when its ID is given as a parameter. From my understanding, when I pass along the object ID in a hidden field, the object gets bound again on the next request and filled with the values that were entered in my form. What am I missing? - Or am I going wrong here in assuming that is the order in which things happen? At first glance I don't see how the hydration scheme is an improvement. It's called before the binding and validation process takes place, which means that it happens before the automatic parameter binding (right?). If I read correctly this means that I have to hydrate the object by myself by using a request parameter and querying my DAO object. So I am basically doing work that Stripes can handle on its own, and I am not even getting the advantage of automatic type conversion. Before looking into this I was using a lazy getter approach for getting my data from the database. I can see that the best practise makes my code a bit leaner because the getters and setters contain less code. It also makes StrictBinding a bit easier because there's one less parameter to bind. But surely, that can't be all there is to it? It's probably one of these things that you have to get your head around but I'm not seeing it yet. I would really appreciate the insight of someone who knows more about this. Thanks.
