Thanks for your reply.

Is there a link where I can find a latest version of classic controls please? What product would you suggest if we were to drop the classic controls all together?

Thanks.

Adding the stack trace again as it wasnt displayed properly in previous post:

Hi:

Thanks for your reply. Our Chrome is uptodate and this issue has been occuring since November.

I m not able to replicate this in your demo page either because this error is happening when all these steps are taken:

1- Chrome is Zoomed-in

2- you scroll down the tree to select an item

3- you try to get the selected item (and save it). This step is not possible in demo.

Here is the error stack trace:

Here is a sample code including the component version:
