Attachment control does not work in Internet Explorer 11
Summary
The Pega-provided Attachment control does not work in Internet Explorer 11 in the application user portal. When users try to attach a file using the Attach File option, the Attachments section does not display the Drag and Drop and Browse controls for adding a file attachment.
Error Messages
Not Applicable
Steps to Reproduce
- In Internet Explorer11, navigate to the attachment flow and choose Attach.
- Observe that the modal dialog opens, but it does not display the Drag and Drop or Browse controls for you to select a file. It displays the OK and Cancel buttons only.
Root Cause
A third-party product issue
The BrowserIsIE When rule recognizes the Internet Explorer browser with the header User-Agent with an MSIE token. In Internet Explorer11 this feature was removed and is no longer supported.
Resolution
Perform the following local-change:
1. In Data-WorkAttach-File class, create a When rule that evaluates the following expression to true.
@contains(@pyGetUserAgent(tools), "Trident")
2. Override the AttachingScreen section present in Data-WorkAttach-File class and add another visible OR condition, for example:
In section Layout for Drag and Drop Files > Select a File, specify Webpage Dialog
Visible When New27 Is True OR Visible When BrowserIsIE Is True
