IFrame's/Divs never removed

[GoogleCodeExporter]

If you have a highly dynamic UI where things come and go, and if those 
things contain the IFrame Html component, the IFrames/Divs that are 
injected into the HTML are never removed.  

If you dynamically add in IFrame components, and then remove them, if you 
look in Firebug, you'll still see the Divs hanging around.

To remedy this I did the following:
1. Added this to IFrame.as:
        private static var FUNCTION_REMOVEIFRAME:String = 
            "document.insertScript = function ()" +
            "{ " +
                "if (document.removeIFrame==null)" + 
                "{" + 
                    "removeIFrame = function (frameID)" +
                    "{ " +
                        "var iFrameDiv = document.getElementById
(frameID);" +
                        "iFrameDiv.parentNode.removeChild(iFrameDiv);" +
                    "}" +
                "}" +
            "}";

2. In createChildren() added:  ExternalInterface.call
(FUNCTION_REMOVEIFRAME);

3. Added a dispose() method that can be called by whoever created the 
IFrame and in there I do the following:
ExternalInterface.call("removeIFrame", frameId);

Perhaps there is a more elegant way to do this (in removed from stage 
perhaps?), but I think you can see what I am getting at.

Similarly, the ExternalInterface.addCallback(frameId + "_load", 
this.handleFrameLoad); callbacks that are added are never removed either - 
unfortunately I do not have a way to remove them.  As far as I can tell 
ExternalInterface doesn't let me remove added callbacks.

Hi Alan,

I had similar problem which I have addressed in a similar way. I also had the 
need to
print the IFrame contents for which I have created a patch and posted into the 
issue:

Both comments noted. I will get round to adding this in and make the 
appropriate 
attributions.
