currentPath is not updated when element position in array changes

See original GitHub issue

When an element’s position in the array changes, this change is not reflected in the currentPath and jsonPointer properties of the change object:


const ObservableSlim = require('observable-slim');
const proxy = ObservableSlim.create([{}, {}]);

ObservableSlim.observe(proxy, changes => changes
  .forEach(change => console.log(change.currentPath, change.type)));

proxy.splice(0, 1);
proxy[0].foo = 'bar';

Before: [{}, {}] After: [{foo: 'bar'}]


0 update
1 delete
length update add

However, it should read add, as the object now is the first item of the array.

@christianliebel I worked on this issue today and I have it very nearly fixed. I’m hoping to push the fix either tomorrow or Monday.

@ElliotNB Looks good, thanks a lot for implementing this fix! I’ve encountered another array-related issue though (at least I think so), but I’ll open another issue for that.

Thank you.
