According to:
http://tapestry.apache.org/tapestry4.1/javascript/index.html
By default, the Shell component will include the core dojo javascript object dojo.js, as well as the new core Tapestry javascript object - core.js. This means that you don't have to worry about how to include dojo or Tapestry javascript on any of your pages, they will already be available.
I'm currently using SiteMesh instead of the Shell component. How would I add dojo to my SiteMesh decorator?
Thanks,
Matt
