navigation children have incorrect active class bug

[DrizzlyOwl]

All children of .flipster__nav seem to have the class flipster__nav__item--current applied to them even if they are not currently selected.

My config is:

flipContainer.flipster({
    itemContainer: flipItemContainer,
    itemSelector: flipItem,
    loop: true,
    autoplay: 3000,
    style: 'flat',
    spacing: -0.2,
    scrollwheel: false,
    nav: 'after',
    buttons: false,
})

Resulting HTML:

[...]
<ul class="flipster__nav" role="navigation">
    <li class="flipster__nav__item flipster__nav__item--current">
        <a href="#" class="flipster__nav__link">0</a>
    </li>
    <li class="flipster__nav__item flipster__nav__item--current">
        <a href="#" class="flipster__nav__link">1</a>
    </li>
    <li class="flipster__nav__item flipster__nav__item--current">
        <a href="#" class="flipster__nav__link">2</a>
    </li>
    [...]
</ul>

I've attempted to recreate the issue, but I'm not getting the same results.

Can you fork it to be more like your setup, or find a way to recreate the bug?

[DrizzlyOwl]

As requested - forked and modified to be as close as possible to my setup.

Ah yes. I do see that. Not sure of the cause... I'll have to dig into the nav code a bit more to debug. Thanks for pointing this out!

[DrizzlyOwl]

I believe it's caused by updateNav() as I can see when a transition starts the classes are removed and then re-added once the transition stops. I think there needs to be a refinement to the index check before adding the class

[shshaw]

The index is checked in the filter call, but I believe the check for the nonexistant data('category') is causing it to return true when the index check fails.

[shshaw]

Ah yes, that's it. Adding a check to see if the category variable is set fixes it. I'll do a little more testing and push a fix, but you can see it working here http://codepen.io/shshaw/pen/JYBKBz?editors=001
