Using Facebook-Login within a @modal-Component

Hey guys,

I'm trying to use the common Lithium Facebook-Login Component (<@component id="facebook.widget.connect-button.secondary" />) within a @modal-Component. The output for the Facebook-Button is rendered correctly and the redirect, which occurs after the Facebook-Login works well.

But, the proper Login-Flow doesn't work, which means that the Facebook-Login Popup never appears. The current flow looks like this:

The user opens the @model-Box and clicks the Facebook-Login Button and after this no popup appears and the user will be redirect.

I also using the Facebook-Button-Component within a Custom Login Page. In this case everything works fine.

Does anyone of have some experience with such an issue?

Thanks and best regards,

Christian
