How do I delete a value from an Object-based associative array in Flex 3?

actionscript-3, apache-flex

Solution

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()];

Problem

I need to remove the value associated with a property in a Flex 3 associative array; is this possible? For example, suppose I created this array like so: ``` var myArray:Object = new Object(); myArray[someXML.@attribute] = "foo"; ``` Later, I need to do something like this: ``` delete myArray[someXML.@attribute]; ``` However, I get this error message at runtime: ``` Error #1119: Delete operator is not supported with operand of type XMLList. ``` How do I perform this operation?
