KnockoutJs v2.3.0 : Error You cannot apply bindings multiple times to the same element

Question

I\'ve just upgraded to 2.3.0 and now I\'m getting the error

You cannot apply bindings multiple times to the same element.

that

Answer 1

In my case, I was adding to a non existing element, or, I was adding bindings to an element that maybe exists, but it's parent did not. Similar to this:

var segDiv =  $("#segments"); //did not exist, wrong id
var theDiv = segDiv.html("
");

ko.applyBindings(someVM, theDiv);

As far as I can tell, this error seems a bit overloaded in the sense that it will fire on a lot of different errors that can happen with the element, like it not existing. As such, the error description can be highly deceptive. It should have probably read:

"Failure to bind bindings to element. Possible reasons include: multiple binding attempts, element not existing, element not in DOM hierarchy, quirks in browsers, etc"
