Support complex initial values
------------------------------
Key: SEAMXML-12
URL: https://jira.jboss.org/browse/SEAMXML-12
Project: Seam XML Bean Config
Issue Type: Feature Request
Affects Versions: 3.0.0.Alpha2
Reporter: Jozef Hartinger
Assignee: Stuart Douglas
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.
