Raymond Feng resolved TUSCANY-1256.
-----------------------------------
Resolution: Fixed
This is fixed by testing if the service.isUnresolved() == true
> NullPointerException when component reference has target of composite
> reference

> Key: TUSCANY-1256
> URL: https://issues.apache.org/jira/browse/TUSCANY-1256
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Model
> Affects Versions: Java-SCA-0.90
> Environment: Windows XP
> Reporter: Simon Nash
> Assigned To: Simon Nash
> Fix For: Java-SCA-0.90
>
>
> A NullPointerException occurs in DefaultCompositeActivator.createWires() when
> a composite's SCDL specifies a component reference with a target attribute
> referring to a composite reference. This is invalid in SCA 1.0.
> The test case org.apache.tuscany.sca.itest.sdodatabinding.DatabindingTestCase
> has this error in greeter.composite.vm (see revision 536691 of
> /incubator/tuscany/java/sca/itest/databindings/sdogen/src/main/resources/generate).
> This error in the test case has been reported as TUSCANY-1255.
> The runtime error occurs because the model contains a service object with no
> InterfaceContract. Here's the stack trace:
> testWSGreet(org.apache.tuscany.sca.itest.sdodatabinding.DatabindingTestCase)
