[flexcoders] Problem migrating from Flex 2 to Flex 3

[sruthi]

Hi we have a component some thing like this. This code works properly with Flex 
2, but when we try to migrate to flex 3 we are getting ERROR 
1067: Implicit coercion of a value of type Array to an unrelated type 
classes.ixrev.industry:ResultObject.
CellData.mxml
-------------
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml"; width="100%" height="100%" 
xmlns:MyComps="common.*">
.....
....
        <mx:Script>
        <![CDATA[
                [Bindable]
                public var result:ResultObject = null;
                ........
                ........

                ]]>
        </mx:Script>
<MyComps:detailListingCommodity id="detailListingId" headerIndex="0" 
verticalAlign="top" result="{result}"/>

</mx:Canvas>

detailListingCommodity.mxml
---------------------------
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml"; width="100%" height="100%" 
creationPolicy="all">
 <mx:Script>
        <![CDATA[
        [Bindable]
        public var result:ResultObject = null;                  
        ..........
        ..........
        ]]>
 </mx:Script>

....
....
</mx:VBox>
I dont't know why it needs implicit coercion, both are type ResultObject. 
Anybody have any idea?

Thanks
