Thanks a lot Kristian, for the archives t5 doc on ServiceOverride is currently here:
http://tapestry.apache.org/ioc-cookbook-overriding-ioc-services.html I 've read it and learned about overriding, but I think that although they 're useful to achieve what I need..., I think as if they were thought to solve more complicated problems. Concisely what I want is to get a Service from a 3rd party module and change one of it's properties, any ideas on the simplest way to do it without instantiating the whole object again?
