Facebook Feed Dialog does not open - facebook

Question

I am building a custom multi friend selector in order to send posts to friend's walls on Facebook based on this tutorial
https://developers.facebook.com/docs/guides/games/custom-muti-friend-selector/
I have been able to load my list of friends and create a CSV list of people I want to post to but the last step of opening the feed dialog is failing and I don't understand why. The dialog does not open.
this is my sendRequest function
var sendUIDs = '';
$('.cbFriendId').each(function(index){
if($(this).prop('checked') == true){
var addId = $(this).attr('value');
sendUIDs += addId + ',';
}
});
console.log(sendUIDs);
openSendDialog(sendUIDs);
}
function openSendDialog(sendUIDs){
console.log('open send dialog');
FB.ui({
method: 'feed',
to: sendUIDs,
link: 'http://www.mydomain.com',
display: 'iframe',
message: 'Hello from My Domain',
name: 'Click to view my app',
caption: 'Hello my app'
},
function (response) {
if (response) {
alert('Post was published.');
console.log('Post was published.');
} else {
alert('Post was not published.');
console.log('Post was not published.');
}
}
);
}
The last console log entry is 'open send dialog'. I get no errors in IE9 dev tools but I do get an 'Unsafe Javascript attempt to access frame ...' error in chrome.
just for sanity sake here is my graph init
window.fbAsyncInit = function () {
FB.init({
appId: '462750593765445', // App ID
channelUrl: '//www.mydomain.com/channel.html', // Channel File
status: true, // check login status
cookie: true, // enable cookies to allow the server to access the session
xfbml: true, // parse XFBML
frictionlessRequests: false
});
};
Also I should mention that the app is in sandbox mode.
Thanks for the help

What you're trying to do is called Send Dialog, So you need to change your method from feed to send and it should work.
Check out their docs for more information: https://developers.facebook.com/docs/reference/dialogs/send/
