It's starting to couple what we want to call the buttons with what the buttons are suppose to do. If the key were the name of the method we want to dispatch, then it would not be a presentation detail. (Instead, we would be embedding a business detail in the the view.) But in practice, the key will be something that makes sense to the Web designer. This then leads to naming the methods to match what the designers want to use for a button key, and so a presentation detail becomes embedded in the method names. Dmitri's approach decouples what we call the buttons from what Actions we call in response. Which is the really the whole point of the struts-config. It's the DMZ where we map logical names to actual classes. In this case, the button key is the logical name, and the path it forwards to is the actual class. > I still feel (and of course this is a preference issue at this point) that > its bordering on, if not already past, putting business-specific logic in > struts-config by doing this kind of thing.

The Actions call business methods and monitor the outcome, but the struts-config is the brains of the operation. The Action senses things like "success" and "failure", but it the struts-config that decides what to do about it. In truth, the struts-config is the "controller", the ActionServlet is just the infrastructure which enables it. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel +1 716 737-3463 -- http://www.husted.com/struts/ -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
