Subject [jira] Commented: (CXF-2626) xmlbean databinding nullpointer
Date Thu, 04 Feb 2010 15:48:27 GMT

    [ https://issues.apache.org/jira/browse/CXF-2626?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12829627#action_12829627

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

> 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.
