Keep Working with Tab-Focused Dialogs (Critical Update)
Where: This change applies to Lightning Experience in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions. Lightning console apps are available for an extra cost to users with Salesforce Platform user licenses for certain products. Some restrictions apply. For pricing details, contact your Salesforce account executive.
When: You can activate this update in Winter ’20. Otherwise, we auto-activate it on February 17, 2020.
Why: Before the Winter ’20 release, all dialogs triggered by a workspace tab or subtab in a Lightning console app took the focus of the entire app. This update makes dialogs require the focus of only the tab that triggered them, allowing users to interact with the rest of the app.
How: To activate this critical update before June 15, 2020, from Setup, enter Critical Updates in the Quick Find box, then select Critical Updates. For Enable Tab-Focused Dialogs in Lightning Console Apps, click Activate.
After the update, when you trigger a dialog, it’s limited to the tab that created it.
