actionscript 3 - Flex 4 two-way data binding on properties of non-matching types -


is there no simple way perform two-way data binding on properties of non-matching types? in example below trying bind 2 properties each other: 1 of type string (text property s:textinput) , other of type number (bar property foo)

package com.example {     public class foo     {         [bindable] public var bar:number;     } }  <?xml version="1.0" encoding="utf-8"?> <s:application     xmlns:fx="http://ns.adobe.com/mxml/2009"     xmlns:s="library://ns.adobe.com/flex/spark"      xmlns:ex="com.example.*" >     <fx:declarations>         <ex:foo id="foo" />     </fx:declarations>     <s:textinput text="@{foo.bar}" /><!-- error @ line --> </s:application>

attempting compile code results in following error:

1067: implicit coercion of value of type string unrelated type number.

i understand why error happens, wondering if i'm ignorant of (perhaps sort of flex 4 metadata) allow attempt @ conversion between 2 types , throwing run-time error if such conversion fails...

the thing able come change type of property bar in foo * (star wild card, prevents type checking @ compile time). i'd still know if there's way keep type...
