# Introduction

# Apache MyFaces CODI to Apache DeltaSpike

## Example Overview

 - [Fullstack CODI to DeltaSpike @ os890](http://s.apache.org/xA)

## Basically unchanged parts

Here you can see features which were added and the concept itself didn't change (only the packages, config keys,...)

### Project-stage

Only the config key changed [TODO]

### Deactivatable and ClassDeactivator

The concept hasn't changed.

### CodiConfig

The concept hasn't changed.

### Annotation literals

The concept hasn't changed. We just added further implementations.

### BeanManagerProvider

The concept hasn't changed. We just splitted the functionality. The util methods are available in BeanProvider and their name and signature have been unified.

## Extended concepts

Here you can see features which were added and the concept itself changed a bit or got merged with concepts from Seam3

### ConfiguredValueResolver

Here we added more flexibility (esp. re-ordering the default lookup mechanisms). See `ConfigResolver`, `ConfigSourceProvider` and `ConfigSource`.

### ProjectStageActivated and ExpressionActivated

We merged them with a feature of Seam3 and now it's called `@Exclude`. That means the basic functionality is still in place (nothing was removed), but the logic is now inverse.

### DefaultAnnotation

(In progress) We merge it with a similar helper of Seam-Solder to provide custom values for annotation attributes.

## Postponed concepts

We couldn't agree on these features. If you find them useful, please contact the mailing-list. If we see that users need it for reasons we might haven't seen so far, we will discuss it again.

### BeanNames

## Dropped concepts

### Java 1.5 Support

## JSF Module

### Type-safe view config

 - Changed names
 - Annotations are optional
