Structuremap 3 multiple decoration

Question

I am trying to create a dependency graph in StructureMap 3 with a chain of decorators:

Each instance has a constructor with multiple arugments, but exactly one argument of an inner IGeocoder, e.g.

public SomeCachingGeocoder(IGeoCoder inner, IFoo somethingElse)

I am hooking them up like this:

For<OviGeoCoder>().Use<OviGeoCoder>();
For<SqlCachingGeocoder>().Use<SqlCachingGeocoder>().Ctor<IGeoCoder>().Is<OviGeoCoder>();
For<RedisCachingGeocoder>().Use<RedisCachingGeocoder>().Ctor<IGeoCoder>().Is<SqlCachingGeocoder>();
For<IGeoCoder>().Use<RedisCachingGeocoder>();

But I get

Bi-directional dependency relationship detected! Check the StructureMap stacktrace below:
1.) Instance of SOAM.Services.IGeoCoder (SOAM.Services.Geocoding.RedisCachingGeocoder)
2.) new RedisCachingGeocoder(Default of IDatabase, Default of IGeoCoder)
3.) SOAM.Services.Geocoding.RedisCachingGeocoder
4.) Instance of SOAM.Services.IGeoCoder (SOAM.Services.Geocoding.RedisCachingGeocoder)
5.) new HomeController(Default of IGeoCoder, Default of IAlertService)
6.) SOAM.Web.Controllers.HomeController
7.) Instance of SOAM.Web.Controllers.HomeController
8.) Container.GetInstance(SOAM.Web.Controllers.HomeController)

Any ideas how to solve this?

DecorateAllWith allows auto-wiring by default and allows stacking decorators in a quite easy way:

For<IGeoCoder>().Use<OviGeoCoder>();
For(typeof(IGeoCoder)).DecorateAllWith(typeof(SqlCachingGeocoder));
For(typeof(IGeoCoder)).DecorateAllWith(typeof(RedisCachingGeocoder));
