I'm willing to use uncached symbols at the moment for 2 reasons. 1) Saving
massive refactoring effor, 2) I really want to know how to do this !
I implemented the following:
> public static void bind(ServiceBinder binder) {
> binder.bind(IDBSymbolSource.class, DBSymbolSource.class);
> //Binding the source to SymbolSource forces me to assign an ID to that
> bind as Tapestry complains about binding the same service interface
> and it makes it easier to contribute to the service (only using it's
> interface). Also the interface extends SymbolSource.
> }
> @Contribute(IDBSymbolSource.class)
> public static void
> contributeDBSymbolSource(OrderedConfiguration<SymbolProvider>
> configuration, @Named("IpkConfig") SymbolProvider ipkConfig,
> @Named("IxConfig") SymbolProvider ixConfig) {
> configuration.add("SystemProperties", new
> SystemPropertiesSymbolProvider(), "before:*");
> configuration.add("IpkConfig", ipkConfig, "after:SystemProperties");
> configuration.add("IxConfig", ixConfig, "after:SystemProperties");
> }
> @Contribute(MasterObjectProvider.class)
> public static void
> setupDBSYmbolObjectProviders(OrderedConfiguration<ObjectProvider>
> configuration) {
> configuration.addInstance("DBSymbol", DBSymbolObjectProvider.class,
> OrderConstraintBuilder.before("Symbol").build());
> }
The DBSymbolObjectProvider constructor is:
> public DBSymbolObjectProvider(IDBSymbolSource symbolSource, @Builtin
> TypeCoercer typeCoercer) {
> this.symbolSource = symbolSource;
> this.typeCoercer = typeCoercer;
> }
I think the following exception is thrown because the *IDBSymbolSource *service
in the constructor needs to be resolved while the *MasterObjectProvider *it
self hasn't been constructed which is reasonable but how can I resolve this
?
