Hello,
I have a combobox using an itemrenderer.
On change I want to display the same itemrenderer ( class )
as the selected item in the combobox.
e.g.:
a combobox with a colors list
on change: show the selected color in stead of the color value
Hope it makes sense : )
Thanks!

Hello,
I want to store an instance of a Singleton class User into a clientside
Shared Object.
Everything turns out allright, that is untill I try this in a class:
user = so.data.User;
This code works fine for me, but ...
If I call the User in another class, eg:
User.getInstance().name
Than
and vice versa ...
I want to store user information ( name, email, ... ) from my User singleton
in my shared object and when the user returns, I want to read the data from
the shared object and put all the values in my User class.
I can do that by going thru al the public setters, but it'd
sure:
package be.webdevotion.business
{
public class User
{
private static var _instance:User;
private var _email:String=;
private var _name:String=;
private var _transformations:Array;
var user:User = User.getInstance();
Can't find the words to describe my problem.
It's not easy, it's difficult to grasp.
Tried that by setting _instance to public earlier today.
I will check it out again.
I give up for now. Six hours is long enough : )
I will use
User.getInstance().name = so.data.user.name;
I allready use
registerClassAlias(be.webdevotion.business.User,User);
to register the User class in the so.data.
This way the shared object knows about the data type ; )

I use the stand alone player to debug.
I've changed the debug paths to *-debug.swf in my

Another method for fixing this can be using project clean.
I also solve my problem by recreating the swf files.
I rename my main app class and set it as default file.
This way the needed files are recreated in the bin folder.
It's a hassle but I'm gonna look into your tip of using:
FlexBuilder -clean -vmargs -Xmx512m
I also ran into these types of errors.
Only thing that works for me is create a new main class
and copy paste the code from the previous main class.
Then I set the latest main class to the default application.
This forces Flex Builder to recreate the swf files and it

When using amfphp or flash remoting for that matter, you'll find out that
you Actionscript code understands your AMFPHP objects and vice versa.
No need to parse data into native Actionscript objects. Agreed,
E4X etc has made this less harsh to use, but you'll still gain a lot on the
client side
Marcello,
Just a little remark:
AMFPHP is heading towards AMF3 support, including RemoteObject.
In alpha stage now, but I don't think it will take long for a final release
any more.
