Hi Senthurkumaran,

The blank page issue when clicking “Open in a new Tab” in the Knowledge Widget could be tied to a couple of known UI/handler bugs.

Here are a few areas you could check to debug and resolve it:

  1. Check the JS Utilities / Platform Version: There is a known platform issue where the openAssignment action fails to resolve the URL context properly for nested widgets, sending a blank payload. This is typically fixed in the latest platform patch releases (e.g., late 8.8.x or '23.x patches) which updated pz-cosmos-ui-utils.js to handle openAssignmentInNewTab correctly.

  2. Verify Section Parameters: If you are using the Buddy/Knowledge widget wrappers, open KMBuddyContainer (or your active widget wrapper section) in Dev Studio. Make sure that the InvokedFrom parameter is explicitly set to KMWidget. If this parameter is missing or blank, the system fails to apply the correct redirect logic when spawning the new window.

  3. Skin Helper Files: Ensure that KMBuddyStyleHelper is explicitly added to the Additional Style sheets in your application’s skin rule.

As a quick test to isolate the issue, have a user try right-clicking the article link and using the native browser “Open link in new tab” option. If that works but the widget icon fails, the issue is with Pega’s internal JavaScript action handler for that icon.

Hope this helps point you in the right direction! If you are still unable to resolve, please respond with any additional details and I’d be happy to assist.
