Sergey Beryozkin commented on CXF-2626:
---------------------------------------
Hi Daniel : can you please post a very simple example which will help me to
reproduce the issue. I just need a JAXRS resource with a single method which
returns/accepts an XMLBeans bean (simplified as needed)
thanks, Sergey

> Key: CXF-2626
> URL: https://issues.apache.org/jira/browse/CXF-2626
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS, OtherDatabindings
> Affects Versions: 2.2.5
> Reporter: Daniel Berg
> Priority: Minor
>
> I ran into this little code in the xmlbeans data binding, that always seems
> to end up in a NullpointerException.
> I have a simple webservice(as simple as they get) using previously generated
> xmlbean from a schema.
> The write method gets called with my xmlbean and a valid writer, calls write
> with MessagePartInfo as null , and a nullpointer exception occurs.
