Is the “pxGenerateExcelFile” activity being called from the BulkExport activity or separately. Also, why have disabled submit on refresh done? Is there any specific reason.
If we are trying to send some file data back to client always better to sent it in new window or to a specific iframe under the DOM. Please try to use open Url in new window with your activity.
@PrakashDeep It’s being called from BulkExport. The activity creates a Code-Pega-List with the data that needs to be exported, and calls pxGenerateExcelFile to do the export.
