hi all,

i am having troubles with calling auth.getSession in my proxy.

It is being called from a iPhone connect client.

When the proxy URL is invocated from the iphone, FB returns a 100 invalid parameter error to the proxy. However the 2nd attempt from iPhone yields success. Both times the proxy is doing the same code, only the auth_token is different.

Doing a good search, shows that this is a problematic method. I have tried everything in code and even called in a iPhone expert to see if the problem is on the iPhone client.

I have concentrated my efforts on the java api being the problem, however i believe the problem lies else where.

I have done the following

1. checked and tested java code
2. checked and test iphone code
3. checked FB application settings.

any help is most appreciated.

------Here is my java code.---------

String api_secret =
FacebookProperty.getString(FacebookConstants.PROPERTY_API_SECRET);
                String api_key =
FacebookProperty.getString(FacebookConstants.PROPERTY_API_KEY);
                String call_back_url =
FacebookProperty.getString(FacebookConstants.PROPERTY_CALLBACK_URL);
                int connectTimeout = 200000;
                //use the xml helper

        // Make sure the user is logged in to Facebook
        String authToken = request.getParameter("auth_token");
        log.info( "FACEBOOK: auth_token?: " + authToken );

                Map<String, Object> model = new HashMap<String, Object>();
                model.put(FacebookConstants.MODEL_WELCOME_SELECTED, true);

                FacebookXmlRestClient facebookRestClient = new FacebookXmlRestClient(api_key, api_secret);

                boolean generateSessionSecret = true; //always true of connect client
                try{

                        facebookRestClient.setConnectTimeout(connectTimeout );
                        String authSessionKey = facebookRestClient.auth_getSession(authToken, true);

                }
                catch (Exception e) {
                        log.log( Level.SEVERE, e.toString());
                        log.log( Level.SEVERE, e.getMessage());

                }
                String rawResponse = facebookRestClient.getRawResponse();

                log.info( rawResponse );

-------the iphone code is -----------

session = [FBSession sessionForApplication:myApiKey
getSessionProxy:myURL delegate:self];

-----------the error is --------------
