changing the type of a element with jaxb/maven

Question

I am trying to generate java classes from a XSD with a XJB. I am running maven plugin maven-jaxb2-plugin in 0.13.1 version. I want to replace an element type by an other type.

Here is an extract of my xsd file:

<xs:complexType name="TestType">
    <xs:sequence>
        <xs:element name="field1" type="xs:date" minOccurs="1" maxOccurs="1"/>
    </xs:sequence>
</xs:complexType>

<xs:complexType name="Test2Type">
    <xs:sequence>
        <xs:element name="field2" type="xs:string" minOccurs="1" maxOccurs="1"/>
    </xs:sequence>
</xs:complexType>

If I want to change field1 from xs:date to something else I have NO error.

Here is an extract from my xjb for this modification:

<bindings node="./xs:complexType[@name='TestType']/xs:sequence/xs:element">
            <property>
                <baseType>
                    <javaType name="com.test.WTKTest" parseMethod="com.test.WTKTest.parse" printMethod="com.test.WTKTest.print"/>
                </baseType>
            </property>
</bindings>

Now if I replace

<xs:element name="field1" type="xs:date" minOccurs="1" maxOccurs="1"/>

by

<xs:element name="field1" type="TestType2" minOccurs="1" maxOccurs="1"/>

and I change my parse and print method accordingly, I obtain this error:

compiler was unable to honor this javaType customization. It is attached to a wrong place, or its inconsistent with other bindings.

I have done some tests and I can change the type of an element iif the initial type is a type from xs namespace else it failed!

Thanks for your help!
