I arrived at the same conclusion when trying to remove my tiles
configuration. I upgraded to tiles 3 in the process and wrote a custom
result handler (sorry a custom "unknown result handler"). It is invoked
when conventions isn't able to find an appropriate result.

 Here is a stack overflow Q & A which covers that process: "How to
Integrate Struts Conventions with Tiles such that the benefit of
conventions is maintained" http://stackoverflow.com/q/16116142/514065
