DirectLink listening to session state method
Hi All, Is there a way to create an @DirectLink that listens to a method on a state object that I have in my session? What I would like to do is: Here the someMethod method returns a string with the name of the 'next' page. Thanks, Willem van Asperen PA Consulting Group Innovation. Responsiveness. Delivery.

RE: subclass or bean?
Thanks for the comments. Building components does indeed sound like the "proper" way to do it. And creating components is not a difficult thing to do. But where can I find some material on these "...Link" classes -- it would be good if there were some explanation or even examples. The code is hard to comprehend.

It depends on exactly what kind of functionality you are working with in these listeners, but I would probably do something similar to: -) If you do have functionality that's not related to the web stuff at all make it a bean that is managed via hivemind, ie make it a service that you inject. http://jakarta.apache.org/hivemind/hivemind/BuilderFactory.html -) Try to avoid subclassing whenever possible. Sometimes it's needed, but often times it usually means there might be a better way. In your case I would do what comes naturally in tapestry when you have common functionality like this, create components. (they can have listeners and do pretty much anything that a page can do ) Wrap all of it in a Border component that itself just wraps these components. Most Border components (you can find ample examples in the tapestry example apps ) wrap Shell Body (custom common fucntionality components, like navigation/etc..) @RenderBody to allow your page to have its content written, and finally a common footer.

subclass or bean?
Hello, I have a set of pages that have very similar behavior. They have listeners like "handleTransition" and "startNewProcess". The first implementation I did was, obviously, to capture all these general functionality into XXX a subclass of BasePage and then sub class my page classes YYY from there. Now I can DirectLink to these general listeners directly. But -- is that the natural way to implement this? Should I not capture the general functionality into a bean that is "injected" into the page? But do I then need to manually wire the listener of the page to the bean's methods? Is there a way to for the XXX page, such that these are true for all descendents of it? Thanks for your thoughts, Regards, Willem van Asperen PA Consulting Group Innovation. Responsiveness. Delivery.
