Re: T5 IOC Questions
Not sure what I was doing wrong, but this works when added to my
AppModule:
public static void bind(ServiceBinder binder) {
binder.bind(ActionRenderResponseGenerator.class,
MyActionRenderResponseGenerator
.class).withId(MyActionRenderResponseGenerator);
}
public static void contributeServiceOverride(
@InjectService(MyActionRenderResponseGenerator)
ActionRenderResponseGenerator myService,
MappedConfigurationClass?,Object configuration) {
configuration.add(ActionRenderResponseGenerator.class,
myService);
}
Thanks to some discussions archived from the list:

I've tried:

None seem to actually override the ActionRenderResponseGenerator.
Very strange.

Re: T5 IOC Questions
Alas, I just gave up. I wrote my own getClassesFromPackage() instead of using ClassNameLocator and went with that. Seems to work.

Re: T5 IOC questions
Ok,
I continue my investigation.
So I think I don't need to override my service but only override my
service configuration.
So my service is :
PageRenderInitializer
and my service configuration is :
contributePageRenderInitializer( ...
As write in the documentation :
The extensibility comes from the fact multiple modules may all
contribute to the same service configuration:
So I override the the contributePageRenderInitializer with :
public void
contributePageRenderInitializer(OrderedConfigurationPageRenderCommand
configuration,
final SymbolSource symbolSource,
final AssetSource assetSource) {
configuration.add(PageRenderSupport, new PageRenderCommand() {
public void cleanup(Environment environment) {
environment.pop(PageRenderSupport.class);
Document document = environment.peek(Document.class);
DocumentScriptBuilder builder =
environment.pop(DocumentScriptBuilder.class);
builder.updateDocument(document);
}
public void setup(Environment environment) {
DocumentScriptBuilder builder = new
MyOwnDocumentScriptBuilderImpl();
environment.push(DocumentScriptBuilder.class, builder);
environment.push(PageRenderSupport.class, new
PageRenderSupportImpl(builder,
symbolSource, assetSource));
}
}, before:*);
}
It's an ordered list so I add the before:* statement to reflect the
order that I can see in the original method.
But this approach don't work : first my method is call twice
And the method throw and exception like :
11:21:18,796 - [SocketListener0-1] ERROR - PageRenderInitializer:
Construction of service PageRenderInitializer failed: Error invoking

Re: T5 IOC questions
Hummm after debug time I found that impossible to me to add in ordered list the same Id (see class Orderer code). So if it's impossible I need to override the component PageRenderInitializer and all the associated configuration. So I continue my investigation with aliasOveridesService. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5 IOC questions
You should be getting an error there, ApplicationDefault's
configuration is a MapString,String.
You override built-in services by contributing to the Alias service
(or the AliasOverrides service).

Re: T5 IOC questions
Humm I'm very confuse with your input. The documentation and the
tapestry code source don't help me too :(
I use the Alias approche like this :

final SymbolSource
symbolSource, final AssetSource assetSource)
{
configuration.add(AliasContribution.create(PageRenderCommand.class,
new PageRenderCommand() {

DocumentScriptBuilder builder = new
MyDocumentScriptBuilderImpl();
environment.push(DocumentScriptBuilder.class, builder);
environment.push(PageRenderSupport.class, new
PageRenderSupportImpl(builder, symbolSource, assetSource));
}
}));
}
But I raise a recursive exception :

Does i need to overide the PageRenderSupport service or only the

Re: T5 IOC questions
Making contributions to the Alias service can be somewhat tricky,
there's a chicken-and-the-egg problem. You're contributing into the
Alias service, but the Alias service is used to disambiguate
injections ... such as the SymbolSource and AssetSource parameters to
the contribution method. That's the recursion. You may have to
perform the injection explicitly, via @InjectService.
