Question: How can I recreate HttpSession (with cookie, on servlet filters) using JSESSIONID from still active session, passed in request?

Thanks for help.

Answer: 
delete doesn't do as much in AS3 as it did in AS2:

However, I think your problem might be solved by simply using toString(), i.e.

```
var myArray:Object = new Object();
myArray[someXML.@attribute.toString()] = "foo";

delete myArray[someXML.@attribute.toString()];

```
Rather than delete it, try setting the value to null.

```
myArray[someXML.@attribute] = null;

```

That way it'll end up the same as any other value in the array that isn't defined.
