Model and view gets out of sync with checkboxes

[hekke]

http://jsfiddle.net/hekke/mmH63/2/

Try clicking the first checkbox - it marks both the first and second as checked, but the model is ok.

Tested in Chrome 15 and Firefox 8

Edit: updated the fiddle with loop over a different array. Then it works??

here is a working version: http://jsfiddle.net/mmH63/4/

In a strange way this is kind of makes sense, but it is not what you want.
The issue is that the ng:repeat keeps the elements in sync with the order
of elements in the array, but there is no way to tell the difference
between the first and second true element, since they are both associated
with three different input elements. So when you change first false into
true, it is not clear for ng:repeat which input element it should remove
and replace with new instance of the true input.

Not exactly sure how to fix that.

But the thing is - it worked in the 0.10.2 release:

In 0.10.3+ there's only a problem when looping over the same array as I'm indexing into. It's easy to work araound, but what scares me is what else is lurking behind this odd behavior. For an updated 0.10.3+ example, see:

it worked because 0.10.3 did not have stable repeaters and so it was not effected by this issue. Stable repeaters is a feature which keeps the array you are iterating over and the elements in sync, which means that adding an object in the middle of the array will cause a new element to be added to DOM at the same position. But if you have an array such as [true, true], and you change it to [true, false] it is not clear what just happened and how should the DOM behave.

That makes sense. I'm content with that explanation.
