You can also use AspectJ within Tapestry using hivemind-aspectj (at JavaForge). You still have to make sure you weave the aspects into your code, but hivemind-aspectj can inject HiveMind services into your singleton (the default) AspectJ aspects. That way, you can inject all of Tapestry's HiveMind goodies into your aspects in case you need them (which you probably will). If you want more information, email me back and I'll see if I can give you an example (the test cases are quite slim, but they do show how it's used).

Thanks for that - I'm on the right track now. I'm now looking for a tapestry method to advise, one that invariably fires once and only per request. Is there such a method?
