Attachment links for recent work object attachments get deleted



User leaves a work object open past the Access time and clicks the Delete button on the pyAttachFieldRequired section. However, the system deletes the Attachment links for the 500 most recent work object attachments with the same value for AttachmentFieldName.

Error Messages

On the Tracer:
Unable to open an instance using the given inputs: DATA-WORKATTACH-FILE MYCO-MYORG-MYCASE-WORK C-1234!20190101T101010.123 GMT 

Steps to Reproduce

  1. Open a work object
  2. Attach a file to the work object using the pyAttachFieldRequired section
  3. Leave the object open till the Access time outs (default is 30 minutes)
  4. Click the Delete button on the pyAttachFieldRequired section

Root Cause

A defect in Pegasystems’ code or rules. The parameters which were not present after a period of idle time resulted in a larger than expected result set when determining the items for deletion.


This issue is addressed in Pega 8.2.5 patch release.
