>          Issue Type: Feature Request
>    Affects Versions: 3.0.0.Alpha2
>            Reporter: Jozef Hartinger

>             Fix For: 3.0.0.Beta1

> Currently, setting the value of a field is limited to the following basic types: {primitives, Date, Calendar, Enum, Class}. This is not enough for complex cases.
> It would be great if any class instance could be configured via XML extension and injected into a field.
> Here is an example
> public class Car {
>    private String color;
>    // getters and setters
> }
> @ApplicationScoped
> public class Garage {
>    private Set<Car> cars
>    // getters and setters
> }
> The garage bean could be configured the following way:
> <p:Garage>
>    <s:overrides />
>    <p:cars>
>       <s:value>
>          <p:Car color="blue" />
>       </s:value>
>       <s:value>
>          <p:Car color="red" />
>       </s:value>
>    </p:cars>
> </p:Garage>
> or maybe even:
> <p:Garage>
>    <s:overrides />
>    <p:cars>
>       <p:Car color="blue" />
>       <p:Car color="red" />
>    </p:cars>
> </p:Garage>
> I can see the execution steps as:
> 1) Check that Car is a dependent-scoped component
> 2) For each element inside p:cars
>    a) obtain a (dependent) Car instance from BeanManager
>    b) set properties of the Car instance
>    c) garage.add(car)
> This is a different approach to configuration compared what the XML extension provides so far. While it is currently possible to configure beans, if this feature request is implemented, it will be possible to configure bean instances separately and use these instances to configure a bean.
