TreeView disregards Observable's inside ObservableArray passed as dataSource

[Danny Fritz]

Is there a way to preserve the UID of ObservableObject's in an ObsrevableArray passed to a TreeView's dataSource?

I want to have a TreeView and ListView that share some observables. This way changing one would change the other too. It works if I pass the same ObservableArray in and bind ListView second, but I want them to have slightly different subsets.

I have a jsfiddle demonstrating the issue: http://jsfiddle.net/zNLNy/1187/

Thanks

Hello Danny,

The object gets wrapped again because the TreeView uses kendo.data.Node as a base object model. Here is the updated sample that uses Nodes all around and does not update the uids.

Also, please note that if you are using TreeView templates and expect them to be updated when the observable objects change, you need to use .get("") methods so that the widget is aware which properties are being used. This has also been applied to the sample.

Yep, changing to kendo.data.Node worked. Good to know template can detect changes too using get.

Thank you so much!
