NullPointerException with hexBinary attribute
---------------------------------------------
Key: XFIRE-887
URL: http://jira.codehaus.org/browse/XFIRE-887
Project: XFire
Issue Type: Bug
Components: Aegis Module
Affects Versions: 1.2.4
Environment: Java 1.5, JAXB 2.0.4
Reporter: Matthew
Assigned To: Dan Diephouse
Priority: Blocker
I used wsgen to create a client proxy (jaxb 2.0). I sent a message that
contained an object with a null value for an attribute. The attribute is
defined as
<xsd:attribute name="info" use="optional">
<xsd:simpleType>
<xsd:restriction base="xsd:hexBinary"/>
</xsd:simpleType>
</xsd:attribute>
It fails. There is no test for null before it tries to marshall the attribute
value.
Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not
invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Could
not marshall type.
org.codehaus.xfire.fault.XFireFault: Could not marshall type.

This is a blocker for clients of my application because typically this
attribute is not supplied. The schema is from an ECMA standard and I can't
change the data type. This particular object is sent on pretty much every call
to my web service.
