Yang ZHONG commented on TUSCANY-1132:
-------------------------------------
2 comments.
2-1. It seems problem found and solved. What's left?
Missing xsi:type seems the problem.
If I understand Fuhwei's most recent comment correctly, registering SOAP
metadata will generate xsi:type therefore solve the problem.
What's left?
2-2. Further thinking of serializing containers, some are unintentional
In some SCA implementation, transported DataObject is contained by SOAP
Envelope.
As a data transportation service, it's fine for SCA to convey DataObject in
any Envelope.
However, SCA sould have removed the transportation container before handing
over DataObject to users.
Otherwise, users will see extra container/exception unexpected for their
business processing.
Such container serializing is unintentional, actually the container should
have been there in the first place.
On the other hand, users do sometimes contain target DataObject.
Serializing containers is intentional in such scenario, therefore current SDO
serialization behaves as designed by including containers.

> With or without the patch of TUSCANY-1131 to fix the problem in
