I don't get exactly what you want to do by "wrapping".
You can replace an implementation of a service by providing another
implementation, but then the old one will not exist in the registry anymore.
But it sounds more what you need is to intercept the services - take a
look at hivemind interceptors...

Hi --
I am trying to wrap some engine service by replacing the configuration
point, tapestry.services.FactoryServices with this definition:
<contribution
configuration-id="service:tapestry.services.FactoryServices">
<service name="home" object="service:tapestry.services.Home" />
<service name="direct"
object="service:transactionalDirectService" />
<service name="page" object="service:transactionalPageService" />
<service name="reset" object="service:tapestry.services.Reset" />
<service name="restart"
object="service:tapestry.services.Restart" />
<service name="asset" object="service:tapestry.services.Asset" />
<service name="external"
object="service:tapestry.services.External" />
</contribution>
I did something similiar to this to replace
tapestry.services.ResponseContributors:
<contribution configuration-id="tapestry.services.ResponseContributors">
<invoker object="service:ScriptResponseContributor" />
<invoker
object="service:tapestry.services.JSONResponseContributor" />
<invoker
object="service:tapestry.services.DojoAjaxResponseContributor" />
<invoker
object="service:tapestry.services.DefaultResponseContributor" />
</contribution>
but for the factoryservices I get :
Error building service transparentpolitics.sessionFactory: Error at
context:/WEB-INF/hivemodule.xml, line 76, column 87: Unable to
construct service tapestry.services.ServiceMap: Error building service
tapestry.services.ServiceMap: Error at

line 53, column 54.
Does anyone have any ideas on how I can do this service wrapping?
