> The JavaBeansDataBinding does not provide an exception handler
> --------------------------------------------------------------
>
> Key: TUSCANY-1515
> URL: https://issues.apache.org/jira/browse/TUSCANY-1515
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Data Binding Runtime
> Affects Versions: Java-SCA-0.90, Java-SCA-0.91, Java-SCA-Next
> Environment: svn revision 563847
> Reporter: Matthew Sykes
> Priority: Minor
> Fix For: Java-SCA-Next
>
> Attachments: javabeans-exception-handler.diff
>
>
> The DefaultDataBindingExtensionPoint explicitly omits classes that extend
> java.lang.Throwable from being associated with the JavaBeansDataBinding.
> Without an association to the JavaBeansDataBinding (or some other "default"
> databinding), fault transformations from POJO exceptions to some other
> databinding do not occur as the transformation chain can't be established.
> The symptom of this is a new TransformationException("Target fault type
> cannot be resolved") getting thrown from the DataTransformationInterceptor.
> After removing the code in the DefaultDataBindingExtensionPoint that
> explicitly omits java.lang.Throwable classes from being associated with the
> JavaBeansDataBinding, an ExceptionHandler needed to be created for the
> JavaBeansDataBinding. An initial, naive implementation is attached as a
> patch. This implementation will simply act as a holder of the original
> exception and return it on createException.
> With these changes the Exception2ExceptionTransformer was able to establish a
> transformation from the JavaBeansDataBinding to a custom DataBinding
> implementation. Further work may be needed in the exception handler.
