TypeError: Cannot read property 'parse' of undefined

[kaliseo]

Hi,

RadListView seems to crash on ObservableArray
Plugin version : nativescript-ui-listview@8.0.1
Platform version : Android v6.1.2

Code sample :
viewModel.set("playlists", new ObservableArray()); viewModel.playlists.push({ name: "test" });

N.B. Removing push does not trigger error, it seems ui-listview is unable to parse ObservableArray.

Template :
<lv:RadListView items="{{ playlists }}" > <lv:RadListView.itemTemplate> <StackLayout orientation="vertical"> <Label fontSize="20" text="{{ name }}"/> </StackLayout> </lv:RadListView.itemTemplate> </lv:RadListView>

Trace :
System.err: An uncaught Exception occurred on "main" thread.
System.err: Calling js method onCreateViewHolder failed
System.err: TypeError: Cannot read property 'parse' of undefined

@kaliseo why using ObservableArray in the first place?

Still, I've tried to reproduce the issue but the push is working on my side - perhaps you could provide a demo project?
