ServiceOverride help wanted

Hi,

I need to override the original HibernateSessionSourceImpl service with 
a modification of mine - MyHibernateSessionSourceImpl. It is 5.3.8 version.

I followed the instructions in 
http://tapestry.apache.org/ioc-cookbook-overriding-ioc-services.html
and replace the example code:

@Contribute(ServiceOverride.class)
public static void 
setupApplicationServiceOverrides(MappedConfiguration<Class,Object> 
configuration)
{
   configuration.addInstance(SomeServiceType.class, 
SomeServiceTypeOverrideImpl.class);
}

with mine:

     @Contribute(ServiceOverride.class)
     public static void 
setupApplicationServiceOverrides(MappedConfiguration<Class<?>, Object> 
configuration) {
         configuration.addInstance(HibernateSessionSource.class, 
MyHibernateSessionSourceImpl.class);
     }

But it throws:

java.lang.RuntimeException: Error invoking service contribution method 
com.mypack.services.AppModule.setupApplicationServiceOverrides(MappedConfiguration): 
Error invoking service contribution method 
org.apache.tapestry5.services.TapestryModule.productionModeOverrides(MappedConfiguration, 
boolean): Service 'ServiceOverride' is configured using 
org.apache.tapestry5.ioc.OrderedConfiguration, not 
org.apache.tapestry5.ioc.MappedConfiguration.


So I changed MappedConfiguration to OrderedConfiguration:

     @Contribute(ServiceOverride.class)
     public static void 
setupApplicationServiceOverrides(OrderedConfiguration<HibernateSessionSource> 
configuration) {
         configuration.addInstance("Default", 
MyHibernateSessionSourceImpl.class);
     }

But it throws:

java.lang.RuntimeException: Error invoking service contribution method 
com.mypack.services.AppModule.setupApplicationServiceOverrides(OrderedConfiguration): 
Service 'ServiceOverride' is configured using 
org.apache.tapestry5.ioc.MappedConfiguration, not 
org.apache.tapestry5.ioc.OrderedConfiguration.

It looks like Catch-22.

So, what is the proper way to override a service implementation?

There's documentation for that:

This is the way i do it and it works

@Contribute(ServiceOverride.class)
public static void
setupApplicationServiceOverrides(MappedConfiguration<Class,Object>
configuration,@Local WebSecurityManager customAuthenticator)
{
configuration.add(WebSecurityManager.class, customAuthenticator);
}

Hi,

Does anybody know how to override a service in Tapestry 5.3.8?

I don't want to use the back door - copy&paste&change the original 
source in the original location and thus force the webserver to use the 
modified class rather than the original one.
