duScrollspy not working and other strange behaviour

[ux-engineer]

Hi,

When I added this to my navigation controller to be run before view change:

$document.scrollTop(top, duration).then(function() {
  console && console.log('You just scrolled to the top!');
});

I get console errors:

Error: $document.scrollTop(...).then is not a function

For some reason "du-scrollspy" is not working at all, no errors in console. I have tried in on several different elements, only one at a time and no other directives or functionalities of this library in use. I encountered the above mentioned error when trying other functionality to ensure the library has been properly loaded as it was failing silently.

Aha, changing scrollTop to duScrollTo solved the first issue as mentioned in the doc. But the main problem is open that why du-scrollspy is not doing anything.

Does the demo work? If so, then you're doing something wrong but it's hard for me to tell what without any code. Can you post a plunker?

I would need scrollspy feature for just so simple task that a sub-navigation element would be applied a class / fixed position after it is scrolled over the top. Perhaps this library is overkill for it?

I just tried to strip the demo off all the scrollspy features except one element having du-scrollspy directive applied. No active class was applied then.

du-scrollspy relies on the href attribute to find it's target so if you remove that you need to define it like this instead: du-scrollspy="anchor"

I found a weird hidden issue in my code that my be relevant to you, mentioned here.

@envision @homerjam what AngularJS version do you have? I have the same issue with Angular 1.5.5

Sorry can't recall what I was using then but certainly pre 1.5.5. Checkout my comment in the other thread - it was down to the component/view/controller being compiled twice for some reason.
