Combo Box Strange Sorting Behavior [Flex 1.5]

Question

The combobox does not sort if i set [Editable=true] using
Flex 1.5.
But works and sort fine and give accurate results if i remove
Editable attribute from <ComboBox> tag.
Initially i hv taken editable combobox and wants to sort the
dataprovider as user enters the letter.
but in vain.
how can i achive the above.
The keyDown event calls the following function:
function
setInitialItem(t:mx.controls.ComboBox,sDataValueInit:String):Void
t.open();
if(sDataValueInit.length==1 && (Key.getCode() >=
65 && Key.getCode() <= 90))
t.dataProvider.sortOn(sDataValueInit,Array.UNIQUESORT );
}else if(sDataValueInit.length==2 && (Key.getCode()
>= 65 && Key.getCode() <= 90))
t.dataProvider.sortOn(sDataValueInit,Array.UNIQUESORT );
}else if(sDataValueInit.length==3 && (Key.getCode()
>= 65 && Key.getCode() <= 90))
t.dataProvider.sortOn(sDataValueInit,Array.UNIQUESORT );
}else if(Key.getCode() == 13 || Key.getCode() ==32){
t.close();
Thanks in Advance!

If U have the list item as a combo box the maximun length property should be equal to the maximum length of the data displayed in the list.
In Ur case,
The length of 'FALSE' is 5.
even the value to be stored is only '0'.
The maximum length of the field should be 5.
I don't think it's a bug. The very purpose of combo box is to let the users enter the new data at run time.
