Hi,
1. Yes, sorry it is 13.2.0.29
2. Our scenario is using AngularJS with MVC. As I can't find exactly where this error is thrown I believe the scenario is using an ng-repeat and inside the ng-repeat there are syncfusion controls, such as a dropdown and treeview. These controls are therefore created dynamically with the data from the repeat. The error occurs (I think) when we delete from the ng-repeat (ie remove an item from the collection). All we doing with the collection is using the splice method on the array to remove that item that is no longer needed. After that occurs we get the "Unable to get property 'tmpl.$newscope' of undefined or null reference" error in the console.
3. Our code is very complicated to send a sample
Cheers ... Rob.
