Drag & Drop feature fails to attach file
SA-30250
Summary
Drag and drop fails to work. No error messages presented to the user.
Error Messages
Viewing the browser console a Javascript Access Denied error can be found.
Steps to Reproduce
Use Out-of-the-box(OOTB) drag and drop attachments feature.
Root Cause
A HFix was installed which pulled other dependent HFixes.
One dependent HFix-25595 delivered enhancements to the busy indicator which allows screen readers to announce a busy indicator is present for visually impaired users. The implementation of this feature did not take into consideration if the Pega application is embedded in an external app (for example .NET application), which would place Pega in an embedded iframe.
When the newly designed busy indicator attempted to be displayed the API used would try to cross iframes which would fail with an access is denied.
Resolution
Apply HFix-30402 which will correct the side effect introduced by HFix-25595.
