I just implemented a component to address a specific need for the SciQ project. They need to have the ability to have dynamic "magazine-like" pages within CAREO, so I whipped up the Template direct action method. This goes one major step beyond the previous Page direct action, which just spewed out text stored in the database.
Template will allow full access to the theming engine, allowing you to embed other CAREO components within the magazine pages (like, for instance, search results or repository objects).
The SciQ theme is rather empty right now, but that will (hopefully) change this week, since content is overdue from the client...
