I have a partially working AutoComplete for comboBoxes working on this. but I’m having lots of trouble for when you don’t make a selection from the DropDownList.
Here’s a way to test it:
click on FUN1’s A comboBox. type in " - ", you’ll see the only choice is -ON.
now don’t click on the choice in the list, just press Enter.
now, go back to that same ComboBox, and click the arrow to open it, and you’ll only see -ON as the choice. The dataProvider has been deleted
Go to another ComboBox and click the arrow without typing to see the list of values that should be there.
Here is the code that I’m using for this functionality.
//in the FUNSModule class file:
A_CB.addEventListener(MouseEvent.MOUSE_DOWN, getCurrentIndex);
A_CB.textField.addEventListener(Event.CHANGE, getEntry);
A_CB.addEventListener(Event.CHANGE, getChoice)
//A_CB.textField.addEventListener(ComponentEvent.ENTER, checkEntry)
//A_CB.addEventListener(MouseEvent.MOUSE_DOWN, setCurrentIndex)
A_CB.editable = true;
/*
private function checkEntry(event:ComponentEvent)
{
CB_UTIL.checkEntry(event, currentIndex)
}
private function setCurrentIndex(m:MouseEvent)
{
currentIndex = CB_UTIL.setCurrentIndex(m);
}
*/
private function getCurrentIndex(m:MouseEvent)
{ CB_UTIL.getCurrentIndex(m); }
private function getEntry(e:Event)
{ CB_UTIL.getEntry(e); }
private function getChoice(e:Event)
{ CB_UTIL.getChoice(e); }
And now the CB_UTIL class file
package

I’ve been stuck on this problem for over a week now,** it’s driving me completely crazy!!!** any help is appreciated. I’ve narrowed the problem down to when the user clicks outside the comboBox without selecting from the list, thus setting the SelectedIndex to -1.
