            After upgrading recently, the browser shows error message as shown in attachment. The scenario is that I have a tree structure and will step through each node, and show or hide a button for each step. Then for each execution, we get the error message in browser console, which is annoying. It worked fine before and not sure if we need to change after upgrading. Can you help me to detect it? Thanks.

    Best regards,

    Hello, James,

    Thank you for the provided screenshot. 

    To be able to assist you can you provide some more details about the widget that is throwing an error.

    - Is it a Kendo UI TreeList or a Kendo UI TreeView?
    - Can you share a snippet of the widget's setup and also off the custom logic which shows and hides the buttons?

    Look forward to hearing back from you.

    Kind Regards,
