[Simple-support] Ordering of Elements when Serializing Subclass Hierarchy.

[Stan C. <sta...@mo...>]

Is there a way to ensure the ordering of the serialized XML elements 
when using subclasses?

Simplified example.

@Root(name = "response")
public class ClassA {

    @Element(name = "code", required = true)
    private Integer code;

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }

    public String getXmlResponse() throws Exception {

        Serializer serializer = new Persister(new Format(4, "<?xml 
version=\"1.0\" encoding=\"UTF-8\"?>"));
        ByteArrayOutputStream out = new ByteArrayOutputStream();

        serializer.write(this, out);
        out.flush();
        return out.toString();
    }
}



@Root(name = "response")
public class ClassB extends ClassA {

    @Element(name = "status", required = false)
    private String status;

    @Element(name = "transactionCode", required = false)
    private String transactionCode;

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getTransactionCode() {
        return transactionCode;
    }

    public void setTransactionCode(String transactionCode) {
        this.transactionCode = transactionCode;
    }
}



In the Simple example above I'm trying to get this:

<?xml version="1.0" encoding="UTF-8"?>
<response>
    <code>200</code>
    <status>Completed</status>
    <transactionCode>101</transactionCode>
</response>

but I get this:

<?xml version="1.0" encoding="UTF-8"?>
<response>
    <status>Completed</status>
    <transactionCode>101</transactionCode>
    <code>200</code>
</response>


Thanks,
Stan
