Nope, haven't tried that yet.
Basicaly what I did to get it to work is to make all my variables in
Flex2 be strings. Then when I assign the value returned from the
CFC, if its a date or number being returned I use String() which will
convert the number or date to a string representation.
<mx:DateFormatter id="StdDateFormat"/>
<mx:CurrenctFormatter id="StdMoneyFormat" precision="2"/>
[Bindable]
public var date_dp:String = new String();
[Bindable]
public var total_dp:String = new String();
date_dp = String(result[0].DATE);
total_dp = String(result[0].TOTAL);
Then in the binding I use a currency formater and a date formater
which seem to take strings or number/dates as acceptable input and
output correctly.
<mx:Label text="{StdDateFormat.format(date_dp)}"/>
<mx:Label text="{StdMoneyFormat.format(total_dp)}"/>

So when a
