(Tapestry v5.3.5) Contributing a non-caching SymbolSource
I need my application to read it's configuration from a database source but I have to apply my own caching mechanism to satisfy flexibility with updating my configuration and performance (Not hitting the database whenever a value is needed)
The service performing the caching mechanism is SymbolSourceImpl. Since I need tapestry to cache the cachable values such as JVM options. I need to contribute another symbol source. But SymbolObjectProvider (Contributed to MasterObjectProvider) holds only one instance of SymbolSource and I cannot override SymbolSource default binding so I thought about contributing a whole another symbol object provider to the MasterObjectProvider just as tapestry did with the default SymbolObjectProvider.
But here comes an issue when I tried to contribute my own symbol object provider:
@Contribute(MasterObjectProvider.class)
public static void setupDBSYmbolObjectProviders(OrderedConfiguration<ObjectProvider> configuration) {
configuration.addInstance("DBSymbol", **DBSymbolObjectProvider**.class, OrderConstraintBuilder.before("Symbol").build());
}
My DBSymbolObjectProvider constructor looks like this:
public DBSymbolObjectProvider(IDBSymbolSource symbolSource, @Builtin TypeCoercer typeCoercer) {
this.symbolSource = symbolSource;
this.typeCoercer = typeCoercer;
}
Tapestry resolved TypeCoercer but it couldn't resolved IDBSymbolSource and threw the following exception which is logical because the MasterObjectProvider isn't yet constructed to resolve IDBSymbolSource.

I don't think you can have an updatable Symbols even if you get your custom SymbolSource to work(I will come back to how you can do that). The reason being how symbols are inserted into the services. They are inserted into the fields and are not transformed into indirect accessor methods. So even if you changed the value, your custom SymbolSource will not be called again to fetch that value.
How to contribute your own SymbolSource
Just decorate the SymbolSource service
public class AppModule {
public SymbolSource decorateSymbolSource(
final SymbolSource symbolSource) {
return new MyCustomSymbolSource(symbolSource);
}
}
With MasterObjectProvider, it doesn't stay a service, it is called as an object. Still if you want to use MasterObjectProvider always use @Local for local services that helps resolve services and prevent recursion.
