Illegal class inheritance loop. Outer class NestedBinaryData may not subclass from inner class: NestedBinaryData -> [Help 1]

[Tomas-Kraus]

Hi

The following xsd snippet contains a legal element "BinaryData" embedded twice with the same name as: <xs:complexType name="DeviceInstance_t"> xs:sequence <xs:element name="BinaryData" minOccurs="0"> xs:complexType xs:sequence <xs:element name="BinaryData" maxOccurs="unbounded"> xs:complexType xs:sequence <xs:element name="Data" type="xs:base64Binary" minOccurs="0"/> </xs:sequence> <xs:attribute name="Id" type="xs:string" use="optional"/> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType>

As xjc generates an embedded Java class BinaryData inside a embedded Java class BinaryData, the java compiler complains that the class DeviceInstanceT.BinaryData.BinaryData cannot shadow teh class DeviceInstanceT.BinaryData. Right;

So in order to avoid this name clash, I am using jaxb binding to change the name of the most inner java class as NestedBinaryData with the following binding

<jxb:bindings version="1.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema" schemaLocation = "knx_project.xsd" node="/xs:schema"> <jxb:bindings node="//xs:complexType[@name='DeviceInstance_t']"> <jxb:bindings node="./xs:sequence"> <jxb:bindings node="./xs:element[@name='BinaryData']"> <jxb:bindings node=".//xs:element[@name='BinaryData']"> <jxb:class name='NestedBinaryData'/> </jxb:bindings> </jxb:bindings> </jxb:bindings> </jxb:bindings> </jxb:bindings>

But xjc complains that: (xjc) on project KNXNetIPServer: Illegal class inheritance loop. Outer class NestedBinaryData may not subclass from inner class: NestedBinaryData -> [Help 1]

In my opinion, this error is invalid because the jxb:class renaming should apply only to the inner most BinaryData element, not the intermediate one.

I am stuck with the same issue on a different schema snippet. Could you have a look?
