So if i got it right, you want a custom ComboBox on several screens
and the only thing that is going to change is the dataProvider, right?
I would do the following:
1. In your custom ComboBox declare a variable like this:
private var _myDataProvider : Array; //or ArrayCollection, as you prefer
2. Create a getter and setter methods
[Bindable]
public function get myDataProvider() : Array
{
return _myDataProvider;
}
public function set myDataProvider(dp : Array) : void
{
_myDataProvider = dp;
this.dataProvider = myDataProvider;
}
3. In the application where you want to include the custom ComboBox,
pass the dataProvider you want to use, like this:
<custom:CustomComboBox myDataProvider="{DataProviderYouWantToUse}"/>
or
var myCustomCB : CustomComboBox
myCustomCB.myDataProvider = DataProviderYouWantToUse
Please consider that "DataProviderYouWantToUse" is the array (or
arrayCollection) that you want to use as dataProvider for your
ComboBox. When setting the myDataProvider, the setter will be called
and the dataProvider will be updated.
Hope this helps you out
