Denis,
The tapestry-captcha library does work, at least in isolation. Have you
tried running with without the Acegi stuff baked in too? Can you turn up
logging to see what HiveMind is trying to wire in when it creates that
CaptchaEngineService? It will tell you what it wires and I'm pretty sure
that it'll tell you why it doesn't wire the other properties (two service
points exist that match the type, maybe).
