Hi,
I have an ArrayCollection as mentioned below.
private var initDG:ArrayCollection = new ArrayCollection([
{fact: "Order #2314", appName: "AA"},
{fact: "Order #2315", appName: "BB"}
{fact: "Order #2316", appName: "BB"}
...
{fact: "Order #2320", appName: "CC"}
{fact: "Order #2321", appName: "CC"}
]);
I want to populate a ComboBox with UNIQUE VALUES of "appName" field from the ArrayCollection initDG.
<mx:ComboBox id="appCombo" dataProvider="{initDG}" labelField="appName"/>
One method I could think is to loop through the Array objects and for each object check and push unique appName entries into another Array. Is there any better solution available?
