RE: [flexcoders] Binding with arrays in Flex 2 beta 2

To be clear regarding 1.5, you can definitely bind to Arrays.  The key
to updating controls is to use the dataProvider API, which the Array
class supports.

aDataProvider.addItem(oItem); //API method WILL update the control
aDataProvider.push(oItem);      //array method will NOT update the
control
aDataProvider[n] = oItem;      //array method will NOT update the
control

I don't know about 2.0

Subject: [flexcoders] Binding with arrays in Flex 2 beta 2


According to documentation, in Flex 1.5, you shouldn't bind your
dataprovider to a raw array object, because array elements do not
broadcast [ChangeEvent]. And therefore the flex controls won't update
itself and refelct the changes.

I just tried to bind an array object to a comboBox dataprovider in
Flex 2. And it seemed that the changes made to the array object did
get updated in the combo box control.

I was wondering if this has been fixed in flex 2 purposly, or due to
some other reasons.

Thanks,

Larry
