Simon Nash resolved TUSCANY-2312.
---------------------------------
Resolution: Fixed
Fixed in r666738 and r666740.
The commit for r666738 also includes a fix for a problem where a conversational
service implementation that calls RequestContext.getServiceReference() was
getting a CallableReference without a conversation object attached.
> Runtime ignores custom callback when using setCallback()
> --------------------------------------------------------
>
> Key: TUSCANY-2312
> URL: https://issues.apache.org/jira/browse/TUSCANY-2312
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Core Runtime
> Affects Versions: Java-SCA-Next
> Reporter: Kevin Williams
> Assignee: Simon Nash
>
> The Java CAA spec states:
> /**
> * Lines 728-732
> * <p>
> * By default, the client component of a service is assumed to be the
> * callback service for the bidirectional service. However, it is possible
> * to change the callback by using the ServiceReference.setCallback()
> * method. The object passed as the callback should implement the
> interface
> * defined for the callback, including any additional SCA semantics on
> that
> * interface such as its scope and whether or not it is remotable.
> */
> I am getting the following error when I try to provide a custom callback
> using ServiceReference.setCallback(). I appears that the runtime has
> injected the client service as the callback rather then the user provided
> callback resulting in the following exception:
> java.lang.IllegalArgumentException: java.lang.NoSuchMethodException: No
> matching method for operation callBack is found on class
