Apologies for the delay - a change was made at the time but wasn't committed pending an internal discussion.

We'll take another look today and get a fix in.

Hello,

I'm struggling with an error where selecting multiple rows in a ListGrid using Shift+click causes an exception when screen reader mode is enabled. As a result, multiselection does not work in screen reader mode.

Problem reproduced also on latest version: v14.1p_2025-12-07/LGPL Development Only

Steps to reproduce:

• Use the SmartClient SDK embedded server.
• Enable screen reader mode by uncommenting: isc.setScreenReaderMode(true); in the /showcase/index.html file
• Open the show case and navigate to any ListGrid
• Try to select a rows range in the grid by Shift+Click

The exception logged in the browser developer tools console:

Uncaught RangeError: Maximum call stack size exceeded
