I'd also like to see integration with SiteMesh, which excels at page decoration (as opposed to Tiles, which excels at page composition). I've been talking to the folks on the SiteMesh mailing list about integration between Tiles and SiteMesh, but that of course, is outside the context of JSF. We could do a lot of cool things in Shale to provide a unification of JSF, Tiles and SiteMesh without reinventing any of those technologies.
Remember that this mindset is the cornerstone of Shale: Shale aims to augment JSF, not reinvent it, and IMO we should take the same approach with other open-source software that we support.

This would be the second attempt but I would like to start a discussion on a Shale subview component extension.
Currently, The shale subview jsf component provides a post-back method to the prerender method on the ViewController. The id attribute of the component is assumed as the managed bean name. This method would be very useful for staging data for the subview and promoting reuse.
The extension would add the following features:
* Fragments of a page could be created using a XML definition and the same node structure would cover all components making it very abstract. A top-level component could be represented by a displayElement node and associated to the logical name of the JSF component using a componentType attribute.
* The describing documents could be digested at application startup and all inheritance resolved at startup. Checks for circular references would be applied.
* Like tiles, the metadata defining the subcomponent tree would support generalization inheritances and also composition inheritance. Top-level displayElement definitions can extend other top-level dislpayElements. Composition is formed using the element node that includes and overrides attributes of the target top-level node.
* It would also allow a token replacement feature of the binding EL so that the metadata describing the construction of a subcomponent tree could be reused on multiple managed bean names. Featured with the Shale life cycle methods on the ViewController, would provide many more reusable view compositions.
This composition technique could be used in conjunction with other methods too. A sample application can be downloaded from the tracking system. I removed the libraries to make the upload possible. The example uses the myfaces JSF implementation and the Shale library.
