Hey @bumbella , need more info what is the error, on what platform, etc. I have a production (non-angular) app that is loading the URLs from via REST and it is working fine.

Can I use observable items? I think this is the problem

[PeterStaev]

@bumbella I'm not sure what you are doing when the app is closed so cant really help you on this. Seems you are updating something which is messing up the widget state. And yes you can use ObservableArray as item source for the widget.

No further response so closing this one for now. In case you still have problems, please provide more details.
