Parameters don't get passed through when logging in through Facebook

This works like a charm:

<a class="btn btn-large btn-info" href="<%= signin_path('twitter', group_id: @group.id, auto_join: 'y') %>">Login with Twitter</a>

However, when using FB it no longer keeps the parameters after logging in. What can I do to make sure my parameters persist through?

<a class="btn btn-large btn-primary" href="<%= signin_path('facebook', group_id: @group.id, auto_join: 'y') %>">Login with Facebook</a>

I’m not sure I fully understand your question. If you’re still having this issue and would like help, would you mind posting a little more info?
