[ http://jira.codehaus.org/browse/JIBX-32?page=history ]
Dennis Sosnoski updated JIBX-32:
--------------------------------
Component: core
Version: 1.0-beta3c
Priority: Blocker
Environment:
Description:
>From the JiBX FAQ:
Q. Why do I get a java.lang.NullPointerException when I try to
marshal a document?
A. The most likely cause is that you've got a null value for an
object that's not marked as optional in the binding definition.
... snip ...
add a pre-get method to that class for debugging purposes
... snip ...
It occurs to me that it's relatively simple to change that NPE to a jibx
exception that identifies that "name" value that was passed into
MarshallingContext.element with a null value so that the user doesn't have to
modify his bindings file just to figure out which item was null (which isn't
always possible, especially when it happens in production).
I've already applied this patch to beta3c (which we're using here); I'll attach
the same patch to this issue.
