End of active support for Cosmos React version 8.6
Valid from Pega Version 8.6
As of the release of Pega Platform™ version 8.8 in October 2022, the early adopter Cosmos React (now Constellation) UI is no longer supported. Consequently, Pega support teams no longer accept assignments and incident reports for the 8.6 version of Cosmos React and DX SDK. Upgrade to a later version of Cosmos React or Constellation to maintain support.
New dynamic setting to manage validation of hidden fields
Valid from Pega Version 8.6.4
Pega Platform™ version 8.6.4 introduces a new DSS setting for Theme Cosmos and other section-based applications. The validateHiddenField setting controls whether the application validates fields that you hide through visibility rules. By default, validateHiddenField is set to true, which means that the application fields are validated for completeness even if they are not displayed in the form. You can also switch off this functionality by changing the setting value to false.
