           Summary: NPN_InvokeDefault() on saved function() doesn't work.
           Product: WebKit
           Version: 416.x
          Platform: PC
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: wbardwel at curl.com


I have a property on the object returned by
NPP_GetValue(NPPVpluginScriptableNPObject) that the JavaScript in my
HTML page sets to a function.  I do an NPN_RetainObject() on what
JavaScript passes to the property setting function but when I later
try to call that function pointer with the NPN_InvokeDefault(<NPP that
object was made with>, <saved function pointer>, NULL, 0, <an
NPVariant>); it fails.

And nothing is put in the JavaScript console about why it failed, so I
have no idea what the problem is.

I found a workaround, which is to call "call" using NPN_Invoke() on
the function as the object and "call" as the method, which does work.
But this case is what NPN_InvokeDefault() is for, so it should work.
