https://bugs.webkit.org/show_bug.cgi?id=40991

           Summary: NPAPI plugins not compatible with Cocoa
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
               URL: http://www.dreamfactory.com
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org

Our new NPAPI plugin is 32/64 bit pure Cocoa

Everything runs great with 32/64 bit FireFox (release candidate Minefield) and 32 bit Safari

However, on 64-bit Safari Cocoa behaves strangely with respect to dialogs

(We sometimes use a system dialog to open a file or perform page setup for printing)

This bug is easy to reproduce. Simply call [NSApp runPageLayout:nil] from any NPAPI plugin. The dialog will come up & work fine but when you click OK it always acts like you clicked Cancel. Bring the dialog up multiple times you will see: your changes are never remembered, because it thinks you clicked cancel every time. Now try the same thing with FireFox 32 or 64, it works fine.

Here is more detail on what is happening

StopModalWithCode always passes a zero to runModalForWindow, no matter what button was clicked

This would happen if we were calling StopModalWithCode on a secondary thread, but we have confirmed that this is not the case: WebKitPluginHost.app is running our plugin on the main thread.

Please fix this and/or let me know how to help.


Thanks,

Bill Appleton
