Hi,
I ran into a NPE with the latest code in the InnerComposite sample. Please
see the stack trace below.
java.lang.NullPointerException

In this case, the qualified name for the target is the component name and
the portName is null and a NPE is thrown.
The SCA spec defines the following syntax for wire-target-URI:
<component-name>/<service-name>
o where the target is a service of a component. The specification of the
service name is optional if the target component only has one service with a
compatible interface
If service-name is not present (portName==null), we should check and pick
the only one service. Am I right?
Thanks,
Raymond
