m-for shows error when array is updated

[AndresSepar]

The error is:

moon.js:333 Uncaught TypeError: Cannot read property '__moon__' of undefined
at removeChild (moon.js:333)
at diff (moon.js:871)
at diff (moon.js:883)
at Moon.patch (moon.js:1905)
at Moon.build (moon.js:1944)
at moon.js:164

Because moon/src/util/vdom.js is passing ...meta.el as undefined:

---

moon/src/util/dom.js

Line:105  let componentInstance = node.__moon__;

moon/src/util/vdom.js

Line:501  removeChild(oldChildren.pop().meta.el, node);
Line:513  diff(oldChild, child, i$1, node, oldVNode);

moon/src/instance/methods.js

Line:219  diff(old, vnode, 0, parent, {});
Line:258  this.patch(old, dom, this.root.parentNode);

moon/src/util/util.js

Line:42 instance.build();

Odd. Can you provide a reproduction jsFiddle or something similar?

[AndresSepar]

Sure... https://jsfiddle.net/andressepar/tp5x5tpx/

Thank you! A reproduction always helps me experiment around with the issue. This happened because of a change in a metadata property of a virtual DOM node.

Thanks a lot!
