Ignacio Silva-Lepe commented on TUSCANY-1620:
---------------------------------------------
I misspoke above about where the databinding interceptor is not being added.
The trace above shows the invocation chain between the notification component
and the composite reference. In particular, it shows the notification component
invoker calling the notification reference binding invoker directly with no
databinding interceptor in between. This is indeed correct, as both ends have
the same databinding.
However, where a databinding interceptor _should_ be added is in the invocation
chain between the traffic advisory producer and the notification component.
Doing a little bit of debugging, I have a break point in
DataBindingRuntimeWireProcessor.process, and in line 116 I can see that the
target contract (a WSDLInterfaceContractImpl) has a single OperationImpl in its
list of operations, which is ok, but this operation has a dataBinding value of
null. This means that isTransformationRequired eventually returns null and no
databinding interceptor is added.
I am not sure what has changed in the last week or so to make this happen, as I
am assuming that the OperationImpl's databinding value was not null before,
since the sample was working.
Any ideas?
