Here is my proposed fix in XMLListAdapter:: addItemAt() : ...
if (length > 0) {
var localLength:uint = source.length();
//Adjust all indexes by 1
for ( var i:uint = localLength; i>index; i-- ) {
source[i] = source[ i - 1 ];
}
}
source[ index ] = item;
...
We may be able to optimize this too. For example, we could check if the
incoming node already has a parent. If it does, then we need to do this work.
If it does not, we could use the older method which is faster.
