Here we have a frameset, and one frame has a button which, when clicked, 
replaces the location of that frame with yahoo.com.

The frame replaces OK, but on both Netscape 6 and the latest Mozilla milestone, 
an error pops up in the JavaScript console: "focusedWindow.location has no 
properties"

This consists of 3 files in the same folder  . View File 1, then click to 
produce the bug.

The exception you see is from the mozilla application code, it's not something
that happens because of something you did on the page, reassigning to XPToolkit.

why toolkit?  ->danm for triage since it is a window call, cc saari for possible
focus involvement

Summary: Exception thrown when frame location is replaced in handler → JS Error: focusedWindow.location has no properties
Target Milestone: --- → Future
The error is coming in function contentAreaFrameFocus in navigator.js,
said function being set up as a capturing focus event listener on the
'appcontent' element.


// When a content area frame is focused, update the focused frame URL
function contentAreaFrameFocus()
{
  var focusedWindow = document.commandDispatcher.focusedWindow;
  if (isDocumentFrame(focusedWindow)) {
      gFocusedURL = focusedWindow.location.href;
      var saveFrameItem = document.getElementById("savepage");
      saveFrameItem.removeAttribute("hidden");
  }
}

If you load any page with a frameset, and then do a right click, and reload a
frame, you will get this error. Any attempt to refer to the location property
of the window will fail. (Maybe it "doesn't have" a location at that point in
the reload???). Offhand, wrapping that block in a try has no ill effects, since
there are more focus events that follow, which do succeed in updating the UI.

Blake, Jag : is this a known problem? (I think it is ...)


See also bug 65963, which reports a similar error in the JS console and also
involves frames.
Either this bug should be a dup of bug 65963 or vice versa.
