Michael Allman commented on CXF-2474:
-------------------------------------

WRT SourceDatabinding, yes, I see that it supports 
javax.xml.transform.stax.StAXSource.  However, it does not support return 
values of type XMLStreamWriterCallback.  Are there plans to support this?  
Writing the response using an XMLStreamWriter is *much* easier than using an 
XMLStreamReader.  If you want, I can work on a patch.

As far as the StaxDataBindingFeature goes, I've written the code but have been 
unable to test it yet.  I will write again when I've confirmed it's working.

Thanks.

> The DocLiteralInInterceptor.handleMessage(Message) method breaks on the use 
> case where the message part is an XMLStreamReader.
> The code seems to assume that line 188:
>                     o = dr.read(p, xmlReader);
> actually "reads" the message XML from xmlReader and advances to the next 
> message part.  Not so when dr is an XMLStreamDataReader.  In that case, o is 
> in fact xmlReader itself.
> We need to check in the while condition at line 195 that o != xmlReader (or 
> come up with a more elegant solution).  I'm attaching a patch that does that.
