Possible to make a *copy* of a RecordSet

Question

i have a SWF that remotes a fairly large RecordSet (~1800
records). It's a list of products and some info about them.
I'm writing some code to let a store administrator associate
products with each other ( so the site says "These other Companion
Prodcuts might interest you"). I therefore have to list one record
set of 1800 products simultaneously in two different data grids.
the first to list the products and load the 'Companion Products'
list. the other to let the admin choose which products to
associate.
Is it possible to COPY a dataset returned from a remoting
call? I have my app working right now but each instance of the
productListDataGrid that I have on my flash movie calls the list
from the server independently. I was thinking it would be more
efficient to call the list once and split it into two copies--one
for each dataGrid. Can this be done?

Answer 1

All you have to do is something like this:
var myRS:RecordSet = myService.getData();
myDataGrid.dataProvider = myRS;
myOtherDataGrid.dataProvider = myRS;
You can put those lines in a function and call it once. If
you get an error when you try to put what came from getData() into
myRS (datatype error), change the code to this:
var myRS:RecordSet = RecordSet(myService.getData());
That casts the return variable into a RecordSet.
I hope this helps.
