Hi- I really like the lifecycle methods provided by the Shale ViewController. However, I'm having trouble coming up with a simple ViewController Mapping for Facelets Compositions (aka Tag files). For example, let's say I've got a reusable Portlet-like panel that contains a list of the user's Todos. This panel shows up on lots of different screens through-out the application. Facelets gives me the ability to extract this common code into a Tag file (just like a JSP tag file). This Tag file also uses a request-scoped ViewController, called the TodoViewController that fetches the Todos from a database. Here is an example: MyHomePage.xhtml->TodoTag.xhtml->TodoViewController MyInboxPage.xhtml->TodoTag.xhtml->TodoViewController The two JSF views MyHomePage and MyInboxPage both have references to the TodoTag. Can anybody help me with a strategy for how to map these Tag files? I want to give the ViewController the lifecycle methods without needing to explicitly track every page that uses the tag file. I can't just do the mapping based on the name of the tag file because the tag file isn't the actual JSF view. I don't want to have another xml file that developers are required to keep up-to-date with this mapping.
Hmm ... the closest analog in Shale today is the way it uses the <s:subview> component tag to provide view controller functionality to a subview. Would it be possible to create a Facelets widget for Subview that could do this? (It might also require extending the default ViewControllerMapper, but that's certainly feasible.) Any ideas are greatly appreciated.
