Have you considered de-incrementing the loop? Take the last one first then
the compression would not change the lesser values. I think this might be more
computationally more efficient if the array was larger than 50.

Subject: [flexcoders] AS help. Multi
deleting from a list.
I am sure there is an easy answer for this but I have tried
a few
things and not sure where to go from here. I have a list that is
populated from an array in a function.
<mx:List id="myStateList"
dataProvider="{statesList.states}"
multipleSelection="true" />
The
array in the list is states:
AZ
CA
NV
MD
NY
I would
like to delete multiple items with one click of a button. So
if I select
CA and MD, I would like to delete them from the list.
My button has
this call.
<mx:Button label="Remove States"
click="statesList.dStates
(myStateList.selectedIndices)"/>
That returns an array of (1,3)
My
Actionscript page (statesList) has this function.
function
dStates(delState:Array):Void {
for ( var i = 0; i < delState.length;
i++){
states.removeItemAt(delState[i]);
}
}
But what happens is that this will delete CA and NY. I
understand why
this is happening (because states is getting reset and the
second
time through the loop, NY is in the 3rd position of the array) so
how
else can I do this.
Thank you for any
help.
