Bug report

The download functionality of the PDFViewer component doesn't work on Apple mobile devices both on Chrome and Safari browsers.

*Note: The above behavior is not represented on Android devices.

Reproduction of the problem

  1. Open this demo iPad or iPhone
  2. Tap on the "Download" icon of the PDFViewer.

Current behavior

Nothing happens when the Download icon is tapped. After this tapping part of the other component functionalities like "open" and "search" stop working.

Expected/desired behavior

When the download icon is tapped a "save file" popup should appear and the user can save the currently viewed PDF file.

i have some problems with the updated pdf viewer.


The new print feature failed after the second print call.

Reproduction steps

  1. call
  2. click on print
  3. abort browser print dialog
  4. call again, there is no content in the print dialog preview or output



Furthermore the search wont work for me, i get only an browser alert and console log entry.

I'd like to ask if you plan to add a feature to PDFViewer allowing opening files secured with an owner password.
