Menu
I've simplified my problem as much as possible. It only happens in Internet Explorer (9 and 10 confirmed). I have a page rendered with this:
<html>
<body>
<span data-bind="text:$data[0].Mileage"></span>
<script type="text/javascript">
window.initChild = function (ko, viewModel) {
window.ko = ko;
ko.applyBindings(viewModel, document.body);
}
</script>
</body>
</html>
My SPA calls
var otherWindow = window.open('myurl', '_blank');
var handler = function () {
otherWindow.initChild(ko, report);
};
if (otherWindow.addEventListener) {
otherWindow.addEventListener('load', handler, false);
} else if (otherWindow.attachEvent) {
otherWindow.attachEvent('onload', handler);
}
I checked, the data arrives in the initChild method allright.
If I bind ANYTHING on the page, I get a HierarchyRequestError on the applyBindings call. My google-fu completely abandoned me on this, I'm completely clueless what's wrong.

As far as I can tell, it was a symptom of this problem: Using Javascript objects across separate windows in IE
basically, no matter HOW I passed the ko object to the child window, something got lost, and when I tried applying bindings, ko itself ran onto a DOM tracking error, and tried to insert something to somewhere it shouldn't have (possibly part of the parent DOM to the child DOM).
The solution was two-fold:
Horrible behavior, IE...
If anyone can come up with an actual explanation on WHY this was happening, I'll accept his answer instead.
