PROBLEM SUMMARY
You want to use a SWF file with a set of own symbols in order to customize Combobox states.
SOLUTION SUMMARY
Use the upSkin, overSkin, downSkin, and disabledSkin style properties of the ComboBox class to apply custom symbols to any combobox. These attributes can be set directly on a ComboBox instance or as part of a CSS style definition.
EXPLANATION
The first thing to do is create a file in Flash and ComboBoxSkins.swf within it to create 4 symbols of type MovieClip with different states of the ComboBox. These symbols should be named: ComboBox_upSkin, ComboBox_downSkin, ComboBox_overSkin, ComboBox_disabledSkin
If we want to put the CSS inline style do the following:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:ComboBox x="196" y="135"
upSkin="@Embed(source='ComboBoxSkins.swf', symbol='ComboBox_upSkin')"
overSkin="@Embed(source='ComboBoxSkins.swf', symbol='ComboBox_overSkin')"
downSkin="@Embed(source='ComboBoxSkins.swf', symbol='ComboBox_downSkin')"
disabledSkin="@Embed(source='ComboBoxSkins.swf', symbol='ComboBox_disabledSkin')">
<!-- PUT HERE THE OPTIONS OF COMBOBOX -->
</mx:ComboBox>
</mx:Application>

A common hurdle a developer may face is dealing with exceptions in BlazeDS. When an exception is thrown in Java, how do we handle this in flex? Here is a simple and flexible approach inspired by Scott Morgan.
1. Create a Java Class that extends RuntimeException.
package com.flexpasta.exception;
public class FlexException extends RuntimeException
{
public FlexException(String message)
{
super(message);
}
}

Understanding Frameworks
It is important to understand what a framework is before you start using one for the first time.
The word “framework” is often misunderstood in the software development field. There are two different types of frameworks, one being application frameworks and the other being architectural frameworks.
For a more in-depth explanation of frameworks, refer to part 1 of Steven Webster’s series of articles at http://www.adobe.com/devnet/flex/articles/cairngorm_pt1_02.html.
