LinkBar was meant to be used with a ViewStack

July 27th, 2009

I had to read the source code for LinkBar and its parent NavBar to understand why my LinkBar wasn't highlighting the clicked item. Turns out, it's because I use an ArrayCollection as a dataProvider. According to the documentation and the source code, it is possible to use an IList (such as an ArrayCollection), a String (that refers to a ViewStack in the current document) or an actual ViewStack object. But, when a selection occurs, LinkBar makes sure that we supplied a ViewStack before allowing the highlight.

Why, I have no idea. All I know is that I want to use an ArrayCollection as my dataProvider and still highlight clicked elements. I extended the LinkBar component with a tiny workaround. Feel free to use it as you wish.

StacklessLinkBar – forgive me if you find the name unoriginal.
