[jira] [Created] (CXF-3732) xjc generates no JAXBElement for nillable element with required attribute

xjc generates no JAXBElement for nillable element with required attribute 
--------------------------------------------------------------------------

                 Key: CXF-3732
                 URL: https://issues.apache.org/jira/browse/CXF-3732
             Project: CXF
          Issue Type: Bug
          Components: JAXB Databinding
    Affects Versions: 2.3.4
            Reporter: Dirk Lattermann


Please consider the following schema:

{quote}
<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.example.org" targetNamespace="http://www.example.org" elementFormDefault="qualified">
  <xsd:element name="root">
    <xsd:complexType>
      <xsd:sequence>
        <xsd:element name="eal" nillable="true">
          <xsd:complexType>
            <xsd:simpleContent>
              <xsd:extension base="xsd:string">
                <xsd:attribute name="att" type="xsd:string" use="required"/>
              </xsd:extension>
            </xsd:simpleContent>
          </xsd:complexType>
        </xsd:element>
      </xsd:sequence>
    </xsd:complexType>
  </xsd:element>
{quote}

Running this through xjc generates a member {{eal}} of type {{Root.Eal}} in {{Root}}, not of type {{JAXBElement<Root.Eal>}}.
This makes it impossible to unmarshal a document like

{quote}
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<root xmlns="http://www.example.org" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <eal att="j" xsi:nil="true"/>
</root>
{quote}

and obtain the value for attribute {{att}} in {{eal}}, since {{eal}} is null. The above XML document cannot be represented in the classes generated by xjc.

This is not a CXF bug but is a JAXB bug.  I've gone ahead and logged an issue with them:
