SA-28544

Summary

The user upgraded to Pega 7.1.9 from PRPC 6.2 and facing issues with MSOFIleTransferButtons control as it displays activity execution success message in a new window and the control from actual window is lost.

This control is used to read contents from excel file uploaded by the users and need a resolution for this at the earliest possible as users are planning to migrate the application to higher environments in a couple of weeks. The issues can be replicated in IE and firefox browsers.

Error Messages

Steps to Reproduce

 

1. Create a starter flow with a flow action screen which uses MSOFileTransferButtons control.
2. Create an activity which uses MSOParseexcelfile to parse the uploaded excel file.
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. 

Resolution

Perform the following local-change: 

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

As a permanent solution, it is recommended to use 'pxAttachContent'.
