[flexcoders] Re: Convert Object to a Value Object
Hi all,
Thanks for your help. I was out for a few days, but today I will
try, using your advises, to solve the problem.
Thank you very much

For those having trouble converting generic objects into class

(Value Objects), I've created an ObjectTranslator.objectToInstance
method to take care of the problem:
http://www.darronschall.com/weblog/archives/000247.cfm
Essentially, it allows you to convert any plain old object into a
class
instance. Usage is as follows:
import com.darronschall.examples.vo.Book;
import com.darronschall.serialization.ObjectTranslator;
// Define an object with properties that mimic the variable names
// inside of the Book class
var bookObj:Object = { title: My Book title, pageCount: 10,
inLibrary: true };
// Convert the generic object into an instance of the Book class
var book:Book = ObjectTranslator.objectToInstance( bookObj, Book )
as Book;
Originally it was written so that JSON behaved more like
RemoteObject
(returning class instances from the server instead of just plain
objects), but the method is generic enough to be useful in a lot
of
situations.
Hope that helps...

[flexcoders] Re: Convert Object to a Value Object
2 more things to consider. Not sure of your particular setup, but, you may want to look at the [Managed] metadata tag. Setup dependent, it may be what you are looking for. Second, and more generally, casts fail when the system cannot convert one type to another. So, take a look at your objects. You mentioned setting the params one by one, a common technique is to build a static method which accepts an Object and returns (by internally assigning the properties) your value object. Just a couple of thoughts, --Mike --- In flexcoders@yahoogroups.com, Shannon Hicks [EMAIL PROTECTED] wrote: Try assigning it via the preferred method: userAccount = event.result as UserAccountVO; Shan _ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of mvbaffa Sent: Saturday, October 28, 2006 2:36 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Convert Object to a Value Object Hi All, This is pretty basic but I cannot find the problem. I have service that returns a userAccountVO. When I receive the result I am trying to convert the event.result, that is an Object, to UserAccountVO and I receive an error: - Type Coercion failed: cannot convert [EMAIL PROTECTED] to com.mvb.boe.-vo.UserAccountVO-. Well the code is very simple like this: var userAccount: UserAccountVO = new UserAccountVO(-); userAccount = UserAccountVO(-event.result)-; In another application I had the same problem but solved it assigning the properties one by one.
