Re: problem injecting service

Hmm, according to the hivedoc those should be (roughly) the same, one is for Tapestry's factory (what your using) and the other overrides factory defaults and (i believe) is meant to be used externally (if i'm reading the docs right).
http://tapestry.apache.org/tapestry4/tapestry/hivedocs/config/ tapestry.services.ApplicationServices.html 

I'll give it a shot though and see if it does something different.

I use the ServiceLink quite often but am not as familiar with the

configuration point you are contributing to. For example, tacos  
plugs in to
the "tapestry.services.FactoryServices" configuration point to add  
special

services:

There is a nice example on how to use ServiceLink component with your

own EngineService in Chapter 8 (Handling File Downloads and

"Enjoying Web Development w/ Tapestry" book.  It also has nice
explanations on the "flow"...
