When looking for symbols, there is only one mention of @inject I could find
(in javadoc vor @Value).

If you look at
http://tapestry.formos.com/nightly/tapestry5/tapestry-ioc/provider.html

the @Value is used without @Inject

on the symbols docs page
http://tapestry.apache.org/tapestry5/tapestry-ioc/symbols.html

@Symbol is not even mentioned, just the expansions ${sth}


Javadoc for @Symbol says:
Used to inject a symbol value, via a symbol name. This is used much like
[EMAIL PROTECTED] Value}


and finaly whn I look at @Value javadoc:
Used in conjunction with [EMAIL PROTECTED] Inject} to inject a literal value, 
rather
than a service


.. hoep you can see my confusion with this ...
the docs could be fixed to make this more clear.

P.S.
after writing this... i looked back at th example on page
http://tapestry.formos.com/nightly/tapestry5/tapestry-ioc/provider.html

and changed my test to:
@Value("${"+InternalConstants.TAPESTRY_APP_NAME_SYMBOL+"}") String appName,

which is then done right by the docs, and problem is the same as with
@Symbol (both without @Inject)
