Hey @wendt88 , can you provide a reproducible example via https://play.nativescript.org or by attaching the app here. I cannot simulate this error in the demo-ng app in this repo.

[mcler]

Having the same issue on my app. Also could not reproduce it on my own.

Hi all

I have the same error, the first time it works fine, but when I return the error appears.

But I have the solution.

In the file
node_modules\nativescript-drop-down\drop-down.android.js
And in the line 73, you can see the function refresh:
**this.android.getAdapter().notifyDataSetChanged();**

If you commented this line, the error disappears, but we do not want to change the operation of the plugin.

So the solution is, in the function pageLoaded or your first function, you need to reset the items of the array.
viewModel.set("items", items);

I hope it works
