[macos 10.15] FileDialog not working in macOS 10.15 Beta

    Details

    • Subcomponent:
    • CPU:
      x86
    • OS:
      os_x

      Description

      ADDITIONAL SYSTEM INFORMATION :
      macOS 10.15 Catalina, Beta

      A DESCRIPTION OF THE PROBLEM :
      When trying to show a FileDialog in macOS 10.15 Beta the dialog doesn't open and I get the following error message:

      2019-07-12 15:26:40.451 java[17097:242412] +[NSXPCSharedListener endpointForReply:withListenerName:]: an error occurred while attempting to obtain endpoint for listener 'com.apple.view-bridge': Connection interrupted

      Looks like in macOS Beta all panels behave as if they were sandboxed. Here are some resources I've found about people having this same issue:

      https://github.com/xamarin/xamarin-macios/issues/6474
      https://www.emaculation.com/forum/viewtopic.php?f=20&t=10249&sid=2b8ec1b2576eece87a89f8dbc2355d89

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Build the simple FileDialog example provided, press the button to open the dialog.

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      File Dialog should open.
      ACTUAL -
      The console prints:
      2019-07-12 15:26:40.451 java[17097:242412] +[NSXPCSharedListener endpointForReply:withListenerName:]: an error occurred while attempting to obtain endpoint for listener 'com.apple.view-bridge': Connection interrupted
