RE: [flexcoders] modelChanged event
Timing is probably your problem. But anyway there's another solution to
accomblish your task you might want to consider. If products is your
dataProvider Array then you can bind to it via
mx:Binding
source=products destination=this.productsChanged /
and handle it via getter / setter properties
public function get productsChanged() : Array
{
return _productsChanged;
}
public function set productsChanged( newProductsChanged : Array)
{
update( newProductChanged );
_productsChanged = newProductsChanged;
}
private var _productsChanged : Array;
in update you can access the updated dataProvider, delegating to other tasks
such as calculating a sum. The textfields could then i.e. bind to simple
properties of your model.
Best,
Alex

Subject: [flexcoders] modelChanged event
Hi,
I have a DataGrid control and use addItem and removeItemAt method to
add and remove items. This works properly. At the same time, I need
to dynamically calculate the sum for certain field in the DataGrid and
bind the result to a text field.
I add a listener for modelChanged event of dataProvider and add a sum
function there. But the sum function never gets triggered at all even
after an item is added, deleted or all items are removed.
The array that binds to the dataProvider will create after a remote
service call. The listener is created at the initialize function of
the appliation. Could this be a problem?
Thanks,
J

RE: [flexcoders] modelChanged event
I think it stems from the use of an array in databinding. One way to fix this is to reassign your dataprovider. Also you could broadcast a model change event upon completion of the changes. This would hopefully then trigger the sum to change. I had a similar issue a while back and Tracy helped me out. http://www.mail-archive.com/flexcoders@yahoogroups.com/msg09669.html -Kent -Original Message- From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Johnny Sent: Wednesday, July 13, 2005 5:45 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] modelChanged event Hi, I have a DataGrid control and use addItem and removeItemAt method to add and remove items.
