folder1

          folder2

                   folder3

1. moving a file from folder1 to folder2 works.

2. moving a file from folder2 to folder1 works.

3. moving a file from folder1 to folder3 works.

4. moving a file from folder3 to folder1 is BUGGED.

I have the issue in my code, but I also tested it in your demo site and it has the same problem.

https://demos.telerik.com/kendo-ui/filemanager/index

I have uploaded a screen dump of the error output from Chrome.

It is in or after the DataBinding event (Comming from Create action), the the error occurs, thus causing the Delete action and refresh of the UI to never occur.

The bug occurs in both Chrome and IE Edge.

Please fix the bug.

Bug report

1. The issue can be replicated if a nested folder is created in the demo service. The screencast here demonstrates the issue.

Current behavior

Two identical requests are sent when the parent folder is selected.

Expected/desired behavior

There should be a single request when navigating to a parent folder, even if it has a nested child folder.
