What is wrong for CallableReferenceImpl?
I got following exception by build 668091:
java.lang.IndexOutOfBoundsException
at java.util.ArrayList.get(Unknown Source)
at org.apache.tuscany.sca.core.context.CallableReferenceImpl.<init>(CallableReferenceImpl.java:122)
at org.apache.tuscany.sca.core.context.ServiceReferenceImpl.<init>(ServiceReferenceImpl.java:83)
at org.apache.tuscany.sca.core.context.ComponentContextImpl.getServiceReference(ComponentContextImpl.java:226)
at org.apache.tuscany.sca.core.context.ComponentContextImpl.createSelfReference(ComponentContextImpl.java:191)
at org.apache.tuscany.sca.core.context.ComponentContextImpl.createSelfReference(ComponentContextImpl.java:159)
at org.apache.tuscany.sca.host.embedded.impl.EmbeddedSCADomain.getServiceReference(EmbeddedSCADomain.java:225)
When I see the code of CallableReferenceImpl.java, I found following:
line 119: if (this.binding == null) {
line 120: this.binding = this.reference.getBinding(SCABinding.class);
line 121: if (this.binding == null) {
line 122: this.binding = this.reference.getBindings().get(0);
line 123: }
line 124: }
Surely in my case, this.reference.getBindings() returns an empty List.
Following is part of my composite:
<component name="BComponent1">
<implementation.java class="....BService1Impl"/>
<service name="BService1">
<interface.java interface=".....BService1"/>
<binding...."/>
</service>
</component>
Does anyone know why that happen, so that I can fix my composite?
Thanks
Gilbert

Hi Gilbert
Did you get anywhere with this? It looks like the runtime is trying to
create a component reference with no bindings on it. Can you give some more
info about your scenario?
