userAccessToken is not set correctly

[confile]

I tried to upload an image to the users facebook wall. The problem is that the first time I try it I get the error below. The second time went fine. The problem seems to be in the userAccessToken which is not set correctly the first time by:

def userAccessToken = facebookContext.user.token 

What is wrong here?

The code I use is:

        try {
            // publish info to facebook wall of user
            // For private data (access token required)
            def userAccessToken = facebookContext.user.token

                        // if no token is available
            if (!userAccessToken) {
                def facebookUser = FacebookUser.findByUser(springSecurityService.currentUser)
                userAccessToken = facebookUser.accessToken
            }
            def facebookClient = new FacebookGraphClient(userAccessToken)

            // Publish an existing remote file by URL to user's Facebook wall
            def linkUrl = "http://www.testurl.com"

            def messageText = "Wall text"
            def publishPhotoResponse = facebookClient.publish("me/photos", [message: messageText], "logo.jpg", new URL(linkUrl).openStream())
        println "Published photo ID: " + publishPhotoResponse.id

        }
        catch(Exception e) {
            log.error "Failed to publish foto on facebook", e
        }

This is the error I got the first time:

Message: Received Facebook error response of type OAuthException: An active access token must be used to query information about the current user.

You should debug you tokens to check their validity.

Use this to check if they are valid: https://developers.facebook.com/tools/debug

By default, token are only valid during 1 hour. You need to exchange it to get longer one (valid during 2 months) if you want to persist to DB.

@benorama how do I get longer tokens with your plugin? And how can I refresh the token?

[benorama]

Use facebookContest.user.exchangeToken(), it will replace the current token (short term) by a long term (2 month) token.

@benorama The problem is that after I loggin with facebook and use facebookClient.publish the error occurs. The token cannot be to old. When I user facebookClient.publish the second time as I wrote above it worked fine.

Do have any idea? Thank you for your help.
