Mark Combellack commented on TUSCANY-2027:
------------------------------------------
Whilst debugging the code, the problem appears to be around the
RuntimeSCAReferenceBindingProvider.
The createInvoker() method is called, which finds the wire and calls
getInvoker()
The getInvoker() method attempts to get the Contract off the target by calling
target.getContract() but the contract is null so it cannot create an Invoker

> I am having problems with a sample application that attempts to use nested
> implementation.composites and references
> I have an application that has:
> A lowest level composite (Called CComposite) that has two promoted references:
> <service name="CService" promote="CComponent">
> <interface.java interface="samples.C"/>
> <binding.sca/>
> </service>
> <reference name="PromotedRefX" promote="CComponent/refX">
> <interface.java interface="samples.X"/>
> <binding.sca/>
> </reference>
> <reference name="PromotedRefY" promote="CComponent/refY">
> <interface.java interface="samples.Y"/>
> <binding.sca/>
> </reference>
> <component name="CComponent">
> <implementation.java class="samples.CImpl"/>
> <reference name="refX"/>
> <reference name="refY"/>
> </component>
> This is then used by another Composite (called BComposite):
> <service name="BService" promote="BComponent">
> <interface.java interface="samples.C"/>
> <binding.sca/>
> </service>
> <component name="BComponent">
> <implementation.composite name="sample:CComposite"/>
> <reference name="PromotedRefX" target="XComponent"/>
> <reference name="PromotedRefY" target="YComponent"/>
> </component>
> <component name="XComponent">
> <implementation.java class="samples.XImpl"/>
> </component>
> <component name="YComponent">
> <implementation.java class="samples.YImpl"/>
> </component>
> This is then used by another composite (called AComposite):
> <service name="AService" promote="AComponent">
> <interface.java interface="samples.C"/>
> </service>
> <component name="AComponent">
> <implementation.composite name="sample:BComposite"/>
> </component>
> I have a unit test that tries to use AComponent. However, when I invoke an
> operation on the Service, I get the following exception:
