Hi guys,
having a bit of trouble overriding my services with T5.2 (build from a
few days ago ... can't use 5.1 due to some bugs that got fixed in
5.2). I have AppModule and a submodule:
@SubModule( { ServicesModule.class })
public class AppModule {
public static void bind(ServiceBinder binder) {
// this works if ISiteService is not bound in
ServicesModule
// binder.bind(ISiteService.class, MySiteService.class);
}
public static void contributeServiceOverride(
MappedConfiguration<Class<?>, Object> configuration) {
// this fails with exception below
configuration.addInstance(ISiteService.class,
MySiteService.class);
}
}
On startup I get an error below about recursive loading of
'ServiceOverride'. MySiteService has a long chain of dependencies, but
nothing is recursive in it. If instead I override with a mock service
with no dependencies, things work. So the culprit here is not the
custom services, but rather Tapestry 'ServiceOverride'. Any idea
what's wrong?
Thanks,
Andrus
