Page Extension (Financial Edge Omnibar?)

Hi,

I am using the full page extension to create a full page. I then added another add-in as a homepage action to open this full page, works exactly how I want it, the RE ominibar shows at the top and makes the page look as if part of RE NXT directly.

I am trying to do the same thing, but on FE NXT. So using the same full page extention, I added a FE Home Page action. However, when I click on the action in FE NXT, the page loads with RE Omnibar at the top.

Does anyone know if I'm doing something wrong, or if the Page extension is for RE Only.
