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)
