wsdl2java generates incorrect @XmlElement(namespace=“…”)

I am using Apache CXF 3.1.7, and the wsdl2java command is generating code with missing/incorrect namespace attributes on the @XMLEment annotation.

Note I generally use four distinct namespaces within each WSDL document, which are as follows:

• Shared data types across many WSDL documents (http://v1_0_0.datatypes.provider.soap.foundation.rps.com)
• Domain-specific data types (http://v1_0_0.datatypes.provider.soap.common.masterdata.rps.com)
• Parameter types (http://v1_0_0.parameters.provider.soap.common.masterdata.rps.com)
• Service types (http://v1_0_0.provider.soap.common.masterdata.rps.com)

This gives a nice separation of data types, and has worked quite well for me with Axis2. I am having issues, however, when applying this approach to CXF. Below is an example WSDL document with the namespaces defined above:

The following generated ConsumerChannelFetchResponse class contains no namespace attribute for @XmlElement annotations, unless I include '-xjc-npa' in the wsdl2java command. When including '-xjc-npa', I then get the incorrect namespaces in the @XmlElement annotation. Both scenarios result in unmarshaling errors on the client side:

Note the namespace in the 'Status' variable @XmlElement annotation for the above code should be:

• http://v1_0_0.datatypes.provider.soap.foundation.rps.com

But is the following instead:

• http://v1_0_0.parameters.provider.soap.common.masterdata.rps.com

A close examination of the comment block prior to the ConsumerChannelFetchResponse class declaration indicates wsdl2java cleary understands the Status type is from the correct class, but the namespace attribute in the @XmlElement does not reflect this.

I've tried generating this class using both the cxf-codegen-plugin plugin, and executing wsdl2java directly from the command line. Both to no avail.
