Hi,
Defaults for Symbols are easy. Just contribute your defaults to
FactoryDefaults, and let the user override them in ApplicationDefaults:
http://tapestry.apache.org/tapestry5/tapestry-ioc/symbols.html
Configurations are different, and have caused quite a few people
problems. There's been talk of adding an override method
MappedConfiguration to allow this, see Howard's comment:
https://issues.apache.org/jira/browse/TAP5-45
You can easily code around this anyhow, it's just a matter of having an
extra service to hold the default configuration.

Alright, so maybe my response below is a little rant/flame. But really,
are you truly saying that Tapestry doesn't allow libraries to properly
set defaults, then allow users of the library to override those defaults??
<rant>
This is a library! A library needs to be able to set defaults, that
users of the library can override for their particular purposes. Else,
every setting becomes required for every user to set!
How does tapestry deal with Symbols? Do we have to always set
tapestry.production-mode, or page pooling configuration? Or with the
"default" mime-type of a page? Would you want to force everyone to set
the mime-type of every page to be "text/html"???
Tapestry MUST support a way to set defaults reliably for Symbols and
configurations reliably, and yet allow users of those to override them!
I really can't see any other way. Are you truly saying that this basic
use case can't be supported?
