getActiveDocument() function retur… | Apple Developer Forums

getActiveDocument() function returns undefined in tvOS, but in sample code doesn't

If you were to take a look at the sample code that the apple docs offer they do something like this in the application.js file:

Code Block function pushPage(page, loading) {
    var currentDoc = getActiveDocument();
    navigationDocument.replaceDocument(page, loading);
}

Code Block
function pushPage(page, loading) {
var currentDoc = getActiveDocument();
navigationDocument.replaceDocument(page, loading);
}

I printed to the console the value of the variable currentDoc and indeed returns the active document.
I double checked that this function is not being declared anywhere else, and it isn't.

However in the tvOS app that I'm working on getActiveDocument() doesn't exists.

What? Why? How?
