I create an iframe with a name (let's call it "aniframe"), and then I remove it. Later, I create a new iframe of the same name. The new iframe has a null .document attribute. Consider the following HTML that exhibits this:
<html>
<script type="text/javascript">
function loader() {
alert(frames['aniframe'].document);
document.getElementById("content").innerHTML = "Hello world";
alert(frames['aniframe'].document);
document.getElementById("content").innerHTML = '<iframe src="" id="aniframe" name="aniframe">';
alert(frames['aniframe'].document);
}
window.onload = loader;
</script>
<body>
<div id="content">
<iframe src="" id="aniframe" name="aniframe">
</div>
</body>
</html>
An easy workaround would be to make the name of the new iframe different (this works fine and has a non-null document attribute).
Reproducible: Always
Steps to Reproduce:
1. Create an iframe
2. Remove it from the document (in the example I changed the .innerHTML of the parent div)
3. Add an iframe with the same name to the document, and look at its .document attribute
Actual Results:
The new iframe has a null .document attribute
Expected Results:
The new iframe should have a non-null .document attribute, of type HTMLDocument.

Your issue here is actually that frames['aniframe'] is still returning the old frame. You can check this by comparing it to what document.getElementById("aniframe") is returning before and after the innerHTML set.
