It's really easy. Use the AS2CFC wizard in FB. Make sure your
RemoteClass metadata is in place in the CFC/AS class.
[RemoteObject(alias="com.mycompany.vo.EmployeeVO")]. Loop through your
CFQUERY and use createObject() to create individual instances of your VO
and populate the properties accordingly., and add each one to an Array.
In your CFC function, you have
returntype=""com.mycompany.vo.EmployeeVO[]".
Assuming you've got the mapping setup correctly and no gotchas you'll
get your datagrid pouplated with your EmployVO's.

ok, i think i'm picking up what you guys are laying down- the DG
dataprovider is an arraycollection that comes straight from a query in
my CFC. that query contains the exact same columns as properties in my
VO, that is why I thought the conversion should happen fine. Seems what
I need is to populate my DG with VO's?? Maybe that is the part I'm
missing, how do I go about doing that?
thanks everyone,
d.

In the example code below I don't even see any
RemoteObject metadata. Also, is the dg's dataprovider of
ArrayElementType EmployeeVO? It's unclear. It's not a question of data
types alone - the metadata must be present for the conversion to work
correctly.

If you dg doesn't contain the same VO's you
think you got from the server, I'd double check the [RemoteClass]
metadata.

coldfusion, but i don't think it matters- i'm
trying to take an actionscript object (the selectedItem of a datagrid)
and cast it to another actionscript object (my VO). i suspected the
mx_internal_uid property on the list item is messing me up, it's the
only property that comes into the VO from the datagrid that the VO does
not have- so i got to googling.
http://blog.smashedapples.com/2008/02/my-boring-base.html
so now i have a base VO class that all my other
VO's extend, and in this superclass I loop over properties and remove
that one, and now- it all works fine.
thanks,
d.

i do get the employee list from a database, and
I tried putting RemoteClass metadata on the VO class with an alias- no
luck- same error.

it's a very simple example of exactly

i tried setting it a property at a time
and that of course works- but i'll have to write much more code and it
will be harder to maintain.

Ok i think you can't do that since I am
looking at Adobe <http://www.adobe.com/> Flex Professional 2.0 wrox
book and they have a similar example and what they did was
EmployeeVO.employee ID =

ok, here is EmployeeVO.as
package com.winn.vo
{
[Bindable]
public class EmployeeVO
{
public var employeeID:uint;
public var roleID:Number;
public var employeeTypeID:
Number;
public var employeeStatusID:

}
}
then in my mxml file i have a simple
datagrid
<mx:DataGrid
id="employeeDataGrid"
width="100%" height="100%"
dataProvider="{ EmployeesModel.
getInstance( ).employeesList }"
>
with a click listener
employeeDataGrid. addEventListener (
MouseEvent.CLICK, clickHandler );
and here is clickHandler
public function clickHandler(
event:MouseEvent ):void
{
var testVO:EmployeeVO =
EmployeeVO(event. currentTarget. selectedItem) ;
Alert.show(testVO.
employeeID. toString( ));
}
and the selectedItem has these
properties.. .
employeeID = 1830 [0x726]
employeeStatusID = 2
employeeTypeID = 1
mx_internal_ uid = "D3C...."
roleID = 3

i tried your first suggestion, the
second one I had already tried- at least with this one I get an error
TypeError: Error #1034: Type Coercion
failed: cannot convert [EMAIL PROTECTED] to com.winn.vo. EmployeeVO.
Still the same question though, the
datatypes seem to be compatible- so why the error?
thanks,

Maybe this will help:
var testVO:EmployeeVO =
EmployeeVO(event. currentTarget. selectedItem) ;
or
var testVO:EmployeeVO =
event.currentTarget .selectedItem as EmployeeVO;
good luck,
