filtered ArrayCollections
not sure if this is an issue or just me not understanding.
when i filter an ArrayCollection (ac), i see its length change to the expected
size based on the filter condition but if i send that filtered ac to my backend
(coldfusion) for reporting the whole, unfiltered ac is passed back. i guess its
passing back the ac array source rather than ac wrapper?
i've already worked around it but curious if this is expected/designed? and is
my workaround "ok" (loop over filtered ac & add items to new array to pass to
backend)?
thanks.

not specifically, passing the ac to remote cf function. underneath i think
remoting is just sending the source array.

thanks i'll benchmark against a simple loop & add--these are small collections
<150 elements.

When you apply filter, only ac get's filtered, ac.source will still be the
same. Looks like you are passing ac.source to your backend?
You may give this a try:
yourAC.filterFunction = yourFilterFunction;
yourAC.refresh();
var filteredArray:Array = ObjectUtil.copy(yourAC.toArray()) as
Array;

probably not worth the effort, i think this is the first time i've needed to do
this in i can't remember when.
thanks.

Yes, it serializes the source, not its current view.

Seems ok. You could also try subclassing and changing what
readExternal/writeExternal does. Maybe some committer will add a flag and
build in the option.
