OpenSAML user discussion

Hello,

I have a question regarding sending a <LogoutResponse>. I assumed this was 
done with the HTTPRedirectDeflateEncoder like this:

...
messageContext.setOutboundSAMLMessage(logoutResponse);
...
HTTPRedirectDeflateEncoder encoder = new HTTPRedirectDeflateEncoder();
encoder.encode(messageContext);


However, i get the following error:  
org.opensaml.ws.message.encoder.MessageEncodingException: SAML message is 
neither a SAML RequestAbstractType or Response

this happens in the following code in the HTTPRedirectDeflateEncoder:
if (messagesContext.getOutboundSAMLMessage() instanceof RequestAbstractType) {
            queryParams.add(new Pair<String, String>("SAMLRequest", message));
        } else if (messagesContext.getOutboundSAMLMessage() instanceof 
Response) {
            queryParams.add(new Pair<String, String>("SAMLResponse", 
message));
        } else {
            throw new MessageEncodingException("SAML message is neither a 
SAML RequestAbstractType or Response");
        }

LogoutResponse is indeed not a subclass of Response but of 
StatusResponseType, so the exception is thrown. I am using the same way for 
LogoutRequests and that works just fine (because LogoutRequest is an instance 
of RequestAbstractType).

So my question is, what am i doing wrong with the LogoutResponse? Do i need 
to send it in another way?

kind regards,

Paul
