  3. Pass this activityname as a parametre in the uploadActivity param.
  4. Create a case and try to upload a excel file using this control.


Root Cause



A backwards compatibility defect in Pegasystems’ code or rules. The control was deprecated and provided a local change to overcome the issue considering the your deadlines.

Perform the following local-change: 

Comment only “parentWindow.name = parentWindow.name +" "+ currentTime;”  in MSOFileUploadHTML rule.
