Hi Alex
I gave it a try and I can see what you are getting at but I would be grateful
for a bit more help.
What I want to do is to -
1. Make copy of the XMLListCollection dataprovider in an array by using
toArray();
2. Remove the sort for XMLListCollection dataprovider.
3. Copy the data back from the array into the XMLListCollection.
I tried the following(InitiativeList is the XMLListCollection):
var iniCopy:Array = InitiativeList.toArray();
var iniXMLCopy:XMLListCollection = new XMLListCollection();
InitiativeList.sort = null;
for (var i:int = 0; i < iniCopy.length; i++) {
iniXMLCopy.addItemAt(iniCopy[i],i);
}
InitiativeList = new XMLListCollection(XMLList(iniXMLCopy.toXMLString()));
InitiativeList.refresh();
It sort of works but for some reason the first drag I do does not work but then
subsequent ones do.
Could you give me an idea of where I am going wrong - I guess there is a better
way than the long winded method I have used anyway.
Thanks a lot.
Chris
