The test case has been run again on Tuscany next, Tuscany 0.99, Tuscany 1.0 RC1 respectively. Looks like it doesn't work. Below you could find the result:

> Nested Callbacks Fail

> Key: TUSCANY-1398

> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Java Implementation Extension

> I created a simple SCA application, which involves an order process. The application was attached. Below is the composite file of the application. Note that, the callback method of Supplier will invoke the callback interface of Customer. Thus, there are nested callbacks.

> However, the application fails on both SCA Java 0.90 and trunk. Below is the error message. When I debugged the application, I found that it might be caused by wrong "from" info in ThreadMessageContext.
