Subject: Composite Reference Example

Can anyone point me to an example that uses a Composite Reference? I
noticed that the one in BigBank is commented out. 

I'm having trouble testing OSGi support against the latest code. I've
got a sample that looks like this:

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0";
           xmlns:osgi="http://tuscany.apache.org/xmlns/osgi/1.0";
           name="Retailer_Warehouse">

    <service name="RetailerService" target="RetailerComponent">
        <interface.java  
             interface="mypackage.Retailer"/>
        <osgi:binding.osgi 
             service="mypackage.Retailer"/>
        <reference>RetailerComponent</reference>
    </service>
    
    <reference name="ShipperReference" override="may"
multiplicity="0..n">
        <interface.java 
            interface="mypackage.Shipper"/>
        <osgi:binding.osgi 
            service="mypackage.Shipper" 
            filter="(objectclass=mypackage.Shipper)" 
            immediate="false"/>
    </reference>

    <component name="RetailerComponent">
        <implementation.java   class="mypackage.RetailerComponentImpl/>
        <references>
            <reference name="warehouse" target="WarehouseComponent"/>
        </references>
    </component>
    
    <component name="WarehouseComponent">
        <implementation.java class="mypackage.WarehouseComponentImpl"/>
        <references>
            <reference name="shipper">ShipperReference</reference>
            </references>
    </component>

</composite>

According to the spec, it should be legal for the target of the
"shipper" reference to be a Composite Reference (in this case,
ShipperReference):

"A composite reference is a valid target of a wire. In this case, the
name of the reference is the
value set on the wire targeting the reference". (pg 24 of the v.95
spec).

However, the composite above fails when ConnectorImpl attempts to locate
the target (the parent's children map contains only components and
services, no composite references). Is the problem with my Composite
definition, or is the problem with Tuscany? 

Thanks,
Joel
