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.

I use the Alias approche like this :
public static void contributeAlias(Configuration<AliasContribution>
configuration,
final SymbolSource
symbolSource, final AssetSource assetSource)
{
configuration.add(AliasContribution.create(PageRenderCommand.class,
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
MyDocumentScriptBuilderImpl();
environment.push(DocumentScriptBuilder.class, builder);
environment.push(PageRenderSupport.class, new
PageRenderSupportImpl(builder, symbolSource, assetSource));
}
}));
}
But I raise a recursive exception :
java.lang.RuntimeException: Failure starting Jetty instance:
org.mortbay.util.MultiException[java.lang.RuntimeException: Exception
constructing service 'ServletApplicationInitializer': Unable to
instantiate class org.apache.tapestry.services.TapestryModule as a

Construction of service 'Alias' has failed due to recursion: the
service depends on itself in some way. Please check
org.apache.tapestry.services.TapestryModule.build(Log, String,
AliasManager, Collection) (at TapestryModule.java:254) for references
to another service that is itself dependent on service 'Alias'.]
Does i need to overide the PageRenderSupport service or only the
DocumentScriptBuilder and what the right way ?
Thank's
