Question

I’m trying to execute callback function in FB.ui (send dialog). It called in same moment when loaded FB.ui but I want execute callback function after pressing ‘send’ or ‘cancel’ button. Is it realizable?

function callback(response) {
      alert('message was sent');
}

FB.ui({
                method: 'send',
                name: 'Dialog',
                link: 'http://***.com',
                redirect_uri: '****',
                description: '***',
                picture: '***',
                to: userId
            },
                callback(response)
            );

Yo, I’m not sure if it’s your case, but it seems there’s a bug when testing on development environments, mostly due an issue related to the port parameter in a url.
