Nativescript-ui-feedback: NativeScript RadListView throws when re-positioning items

[tsonevn]

_From @bryce-marshall on June 7, 2018 0:31_

Which platform(s) does your issue occur on?

Android
I am testing on Android 5.1

Please provide the following version numbers that your issue occurs with:

• CLI: 4.1.0
• Cross-platform modules: 4.1.0
• Runtime(s): tns-android: 4.1.1
• Plugin(s):
  "nativescript-ui-listview": "^3.5.6",

Please tell us how to recreate the issue in as much detail as possible.

When scrolling a RadListView component with item-reorder enabled AFTER one or more items have been reordered, an exception occurs.

UPDATE:
Recreating the layout on the itemReorder event (as described here) does prevent the exception, however it is not a suitable workaround because:

1. It resets the list scroll position
2. The exception also occurs when the view scrolls as a consequence of dragging a list item for reordering (i.e. before the reorder event has occurred)

Stack traces below.

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.

Any news on this ? I have the same problem here

[ChristofferSkog21st]

How is this still not fixed? It's breaking the entire app for us on Android and there's no way to solve it..

[BlueHunter99]

Are there any options to fix this? Building a reorderable list from scratch might be a little outside of my own capabilities.

[adeepak7494]

Is there any hope that the issue get's resolved.
