Issue

On clicking the pyWorkAttachmentIcon control, the attachment preview does not display.

Symptoms and Impact

The attachment cannot be previewed.

Steps to Reproduce

1. Log in to the Pega application as an operator whose username contains one or more special characters.
2. Add an attachment to a case.
3. Click the pyWorkAttachmentIcon control to preview the attachment.

Root Cause

This is a Pegasystems defect. The attachment preview does not display when the username of the operator (who added the attachment) has special characters.

Solution

Perform either of the following:

• For UI Kit based applications, update to Pega Platform™ 8.8.4.

• For Theme-Cosmos based applications, perform the following steps:
  1. In pyAttachmentFeedDescription, add after line 80: "uploadedBy = uploadedBy.replace("'", "\\'"); " //replace ("single quote", "backslash + backslash + single quote");
  2. In pyWorkAttachmentIcon, add after line 129: "uploadedBy = uploadedBy.replace("&#39", "\\&#39"); " //replace ("&#39", "backslash + backslash + &#39");
