                 Key: CXF-2083
                 URL: https://issues.apache.org/jira/browse/CXF-2083
             Project: CXF
          Issue Type: Bug
    Affects Versions: 2.1.4
         Environment: Java 1.5, Spring 2.5, CXF 2.1.4, Any OS.
            Reporter: Knut Ivar Skogland


Background: 
I have a Xfire project which I'm porting to CXF. Using the Document-First approach and using XMLBeans. We have one xsd that imports other xsd's for each "domain". Every "domain" xsd contains requests and responses which imports datatypes from underlaying schemas with different namespaces.
This works with JAXB (And Xfire with XMLBeans), but not with CXF and XMLBeans.

I have simplified a test project.
The structure is like this;

PublishedFacade.xsd              -- imports sum.xsd
         | ---- sum.xsd                -- contains request and responses. Imports types.xsd.
                     | ---- types.xsd  -- contains complextypes and simpletypes for XMLObject validation

There were a similar error using xs:include (https://issues.apache.org/jira/browse/CXF-1700), but I can't use include as the wsdl will be different when the namespaces changes. My wsdl's should not change.

Project that "explains" the issue is found here: http://www.knutivars.net/cxf/code/CXFTestXmlBeansXSD.rar
