I'd be interested in some code snippets as to how you extend the business object with the navigateTo method - we have aspect-classe, and have a central map, where the aspect will be retrieved from (cached for the associated object) if the developer desires so.

Hi Martin, I have designed my application in the classical obejct-oriented way so that each use case has a controller, some boundary objects (JSF pages) and entities. I believe your page-bean is the controller for your application use case. I do not see how you can avoid a controller, unless you go back to lumping everything into one object. I have a navigation aspect for each business object. This aspect introduces a navigateTo() method into the object, which contains the logic for navigation. I.e. returns the String to be used in the navigation case. I have not tested this with an object which can be used over multiple pages yet. Note this is a pet project, so I will be making slow progress.

Manfred and me have been working on what we call "Lightweight aspect-oriented JSF-UIs" ;) where each business-object is automatically wrapped in a JSF-enhanced aspect, if necessary. We still have a page-bean, though. for storing the aspects, if nothing else. regards, Martin On 8/23/06, Conway. Fintan (IT Solutions) <[EMAIL PROTECTED]> wrote: > I have to disagree.
