Hi,
if i do this:
DataProvider.Initialize(Array);
and var layers = new Array();
it works just fine. Don't know if this is the accepted way to go about it
though ;)).
As for as i know i thought DataProvider was some kind of adapter class for
arrays not really meant to be instantiated on its own.

Hi Folk,
I can't believe I'm having trouble using a dataprovider, but well... I am.
If somebody could lend me a brain I would appreciate it. Mine apparently is
having some problems. Here is the most reduced case. This code is in the
main timeline.
import mx.controls.listclasses.DataProvider;
var layers = new DataProvider();
layers.addItem({guy:"a"});
var thingtestLength = layers.getItemAt(layers.length);
var thingtestItem0 = layers.getItemAt(0);
var thingtestItem1 = layers.getItemAt(1);
trace(layers.length); // returns "undefined"
// but this one which uses layers.length to get the item
trace(thingtestLength.guy); // returns "a"
// these both just return undefined
trace(thingtestItem0.guy); // returns "undefined"
trace(thingtestItem1.guy); // returns "undefined"
So the item is being filed with an "undefined" key.
I thought that maybe we needed to have a label and tried this as well, but
with the same results.
layers.addItem({label:"joe", guy:"g", data:"a"});
and
layers.addItem({label:"joe2", data:{thing:"a2"}});
with the same results
Does this make sense to anyone?
By the way I also tried
var thingtestLength = layers.getItemAt(layers.length-1);
as that is what is supposed to be the proper syntax, but that gets us
"undefined" as well.
And of course I tried getLength() as well and I tried using
DataProviderClass as well in desperation. I also tried "dataProvider" with a
lower case d as that shows up syntax highlighted but then the compiler says
it cant find the file. It's been years since I've been this bewildered with
something not working. I even uninstalled and reinstalled flash thinking
that my configuration must be broken, but no. It seems to be me.
Thanks for any thoughts.
