Hi @Aniket Gaurikar 

What is the purpose of Isolate script checkbox in client script? It manages whether DOM manipulation should be enabled/disabled for client script. If DOM manipulation code is not working then there is possibility that this checkbox is true which is forcing client script to run in strict mode.

Isolate script" field in client script which is new Feature London version

New client-scripts are run in strict mode, with direct DOM access disabled.

Access to jQuery, prototype and the window object are likewise disabled. To disable this on a per-script basis, configure this form and add the "Isolate script" field.

To disable this feature for all new globally-scoped client-side scripts set the system property "glide.script.block.client.globals" to false..

Hi @Aniket Gaurikar ,

This is very rarely used and needs lot of causion before use. It's generally not recommend to use. This checkbox is used when you playing with Data objects. I hope this helps..
