> Source code of generated *Fault* class is attached to the issue.
> (!) I use JAXB mapping so the patch offered in CXF-3763 doesn't help in my case because it's applied to *TypeClassInitializer* while my client runs on another _ServiceModelVisitor_ descendant - *JAXBContextInitializer* class.
> (i) During debugging of *JAXBContextInitializer* I've found out that every time when *begin()* method triggers for a _MessagePartInfo_ describing a fault, it immediately returns because *getTypeClass()* on the _part_ returns *null* (see _org.apache.cxf.jaxb.JAXBContextInitializer:77_).
> AFAIU the method should continue execution to line 82 where the part would be marked as custom exception.
> (+) Some WSDL excerpts
> WSDL Fault message:
> {code:xml}
> <wsdl:message name="Fault">
> <wsdl:part name="fault" element="fault"/>
> </wsdl:message>
> {code}
> XSD Fault element:
> {code:xml}
> <xs:element name="fault">
> <xs:annotation>
> <xs:documentation>Comment describing your root element</xs:documentation>
> </xs:annotation>
> <xs:complexType>
> <xs:sequence>
> <xs:element name="faultcode">...</xs:element>
> <xs:element name="faultstring">...</xs:element>
> <xs:element name="faultactor">...</xs:element>
> <xs:element minOccurs="0" name="detail">...</xs:element>
> </xs:sequence>

> {code}
> Example of WSDL operation description:
> {code:xml}
> <wsdl:operation name="BonusConversionState">
> <wsdl:input name="BonusConversionStateRequest" message="tns:BonusConversionStateRequest"/>
> <wsdl:output name="BonusConversionStateResponse" message="tns:BonusConversionStateResponse"/>
> <wsdl:fault name="Fault" message="tns:Fault"/>
> </wsdl:operation>
> {code}
> Additional info can be provided if needed.
> Any suggestion on how to workaround the problem would be also appreciated.
