Neeme Praks commented on TAP5-223:
----------------------------------

some code from my side:

{code:java}
   public static void contributeSymbolSource(
      OrderedConfiguration<SymbolProvider> configuration,
           �...@applicationdefaults
            SymbolProvider applicationDefaults,
           �...@factorydefaults
            SymbolProvider factoryDefaults,
           �...@injectservice("Context") Context context) 
    {
     
     configuration.add("ZpsSymbols",
       new ContextResourceSymbolProvider(context, 
"WEB-INF/conf/zps-web.properties"));
    }
{code}

Gives error:
Caused by: java.lang.RuntimeException: Exception constructing service 
'Context': The constructor for module class org.apache.tapestry5.services.Tapest
ryModule is recursive: it depends on itself in some way. The constructor, 
public org.apache.tapestry5.services.TapestryModule(org.apache.tapestry5.ioc
.services.PipelineBuilder,org.apache.tapestry5.ioc.services.PropertyShadowBuilder,org.apache.tapestry5.services.RequestGlobals,org.apache.tapestry5.se
rvices.ApplicationGlobals,org.apache.tapestry5.ioc.services.ChainBuilder,org.apache.tapestry5.services.Environment,org.apache.tapestry5.ioc.services.S

e.tapestry5.services.EnvironmentalShadowBuilder,org.apache.tapestry5.internal.services.EndOfRequestEventHub),
 is in some way is triggering a service b
uilder, decorator or contribution method within the class.

And in this case, the context is null:
{code:java}
   public static void contributeSymbolSource(
     OrderedConfiguration<SymbolProvider> configuration,
           @ApplicationDefaults
           SymbolProvider applicationDefaults,
           @FactoryDefaults
           SymbolProvider factoryDefaults,
           @InjectService("ApplicationGlobals") ApplicationGlobals globals) 
   {
    
    configuration.add("ZpsSymbols",
      new ContextResourceSymbolProvider(globals.getContext(), 
"WEB-INF/conf/zps-web.properties"));
   }
{code}

Any other ideas are highly appreciated.
