1231878 - Getting nsIDOMWindow from nsIChannel e10s -- 2

Status: RESOLVED DUPLICATE of bug 1230062

(Firefox :: Untriaged, defect)

Description

[Andrey]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; rv:11.0) like Gecko

Steps to reproduce:

The next code

var browser = objChannel.notificationCallbacks
													.getInterface(Components.interfaces.nsILoadContext).topFrameElement;
	var window = browser.contentWindow.QueryInterface(Components.interfaces.nsISupports);		 // *** CPOW ***

does not work without shim.

Without shim gBrowser.contentDocument =NULL; // https://developer.mozilla.org/en-US/Firefox/Multiprocess_Firefox/Limitations_of_chrome_scripts

Is there any way to get the window of a request from channel in e10s or all old ways are unsupported without shim?


Actual results:

CPOW 


Expected results:

nsIDOMWindow

My end goal is from channel get a node (IDOMNode) which sent request and to work with its sizes and position.
I have to reliaze chain channel->nsIDOMWindow->nsIDOMDocument->IDOMNode.

> window.gBrowser.getTabForBrowser(browser).
Its will chrome tab but I need a content object for getting nsIDOMWindow of cannel.
I something do not understand. (:

I thought that having a window identifier windowID can I get a window object nsIDOMWindow. or not?

Getting of Components.classes["@antff/event_gateway;1"].getService( Components.interfaces.IFFEvent );
in content script give error (TypeError: Components.classes['@antff/event_gateway;1'] is undefined)

*** chrome
var Gateway = 
{
  Init : function() 
  {
    obj.addMessageListener( "antff@get_parent_obj",        this );
  },
  receiveMessage: function ( mes ) 
  {
    switch ( mes.name ) 
    {
      case "antff@get_parent_obj":
        ............
        break;
    }
  },
  VTContentScript : function() <-- it is  a content injected script
  { 
    addMessageListener("antff@get_parent_obj", function ( message ) 
    {
      !! Here is error - TypeError: Components.classes['@antff/event_gateway;1'] is undefined 
      var antFFEvent = Components.classes["@antff/event_gateway;1"].getService( Components.interfaces.IFFEvent ); <--   it my component
      
			
			I would want to send a window object to IFFEvent
      antFFEvent.some_function( window );
  },
  MarkDoc : function( channel ) 
  {
    if ( channel.notificationCallbacks )
    {
      var loadContext = channel.notificationCallbacks.getInterface( Components.interfaces.nsILoadContext );
      if ( loadContext && loadContext.topFrameElement )
      {
        var windowMM = loadContext.topFrameElement.messageManager;
        windowMM.loadFrameScript( "data:,new " + this.VTContentScript.toString(), true ); <-- inject of content script
        windowMM.sendAsyncMessage( "antff@get_parent_obj", {} );
      }
    }
  }
  ...............
}
Gateway.Init();
