ApplicationDefaults is only one of many SymbolProviders, you don't need to
configure that specific SymbolProvider to set the supported locales.
There are other options, including support for .properties files or system
properties.
I prefer context parameters myself, everything should "just work" if you
add it to web.xml like so:
<context-param>
<param-name>tapestry.supported-locales</param-name>
<param-value>en,de</param-value>
</context-param>
The ServletContextSymbolProvider will handle the rest for you.
I'm sure you're already doing this for other symbols, at least
"tapestry.app-package" :)

Hi List,
I would like to replace the constant Strings in the method
"contributeApplicationDefaults" in my AppModule. E.g. replace the
following line:
configuration.add(SymbolConstants.SUPPORTED_LOCALES, "en,de"); // don't
like the "en,de" here. Would like to replace it.
with something configurable in a text file. I thought providing the
values in web.xml either as context-param or as init-param for the
TapestryFilter was a good idea.
My first try was to inject the Context service as additional parameter
to the contribution method to get access to the context-params. That did
not work. The parameter is null and Tapestry throws an exception. Same
with ApplicationGlobals.
I then browsed through Tapestry's source code and found out that I could
implement my own filter inheriting from
org.apache.tapestry5.TapestryFilter. So my next try was to do that and
override the method "protected void init(Registry registry )". My hope
was to be able to do something sensible with the
javax.servlet.FilterConfig that is returned by getFilter(). But I have
no clue, what to do.
