If you call removeItemAt(0) on a DataGrid, it modifies the underlying DataProvider object. If you don't want it modified, you should assign a copy to it. Try this: assign the same DataProvider to two DataGrid instances, and then call removeItemAt(0) on one of the DataGrid's. The contens of both the DataGrid instances will be in sync because they both refer to the same data. Yahoo!

That creates a shallow copy. If you ever want to deepcopy _and_ have
circular references resolved, then I wrote something that seems to
work well:

RE: [flexcoders] Reloading Data Question
Also, you don’t use binding braces
in AS script:
lstElements.dataProvider = "{catalog.product}"
I’d do something like:
var oDPInitial:Object = catalog.product.clone();
Then in Reload:
lstElements.dataProvider = oDPInitial;

Maybe try doing
dataProvider=”{catalog.product.clone()}”. Basically the
problem is that you’re messing with your original dataProvider and
deleting everything in it. You need to pass your TileList a copy of the
dataProvider so that you can muck with it without doing permanent damage.

How? Cuz my code just isn’t working.

Hi Matt,
Thanks for the info, but I’m a very
new to ActiveScript. Any chance you have some code examples of making a clone?
Or is it going to be some like…
var objData:Object;
objData = catalog.product.clone();
