Re: Use of references with multiplicity *..n?

[Jim Marino]

They should be working for Java types.  Could you open a Jira and  
post the two component classes (particularly the interfaces) you are  
trying to wire together along with the SCDL? I'll try and take a look  
this weekend.

when I try to use the following component impl:

@Service(Retailer.class)
public class RetailerComponentImpl implements Retailer {

    @Reference(name="warehouses", required=true)
    private List<Warehouse> warehouses;

    public void submitOrder(String order) {
        for (Warehouse warehouse : warehouses) {
            warehouse.fulfillOrder(order + ", submitted");
        }
    }

}

for the following set of definitions:

    <component name="RetailerComponent">

class="org.apache.tuscany.samples.supplychain.RetailerComponentImpl"/>
