(was: 3.1.0.CR1)
Add support for activating beans based on the JSF project stage
---------------------------------------------------------------
Key: SEAMFACES-185
URL:
https://issues.jboss.org/browse/SEAMFACES-185
Project: Seam Faces
Issue Type: Feature Request
Affects Versions: 3.0.2
Reporter: Christian Kaltepoth
Assignee: Christian Kaltepoth
Fix For: 3.1.0.Beta4
Hey all,
I think it would be a great enhancement if Seam Faces could support activation of beans
only in specific JSF project stages. MyFaces CODI supports a similar feature with the
{{@ProjectStageActivated}} annotation.
Examples:
{code}
@ProductionStage
@ApplicationScoped
public class ProductionEntityManagerProducer {
...
}
@DevelopmentStage
@ApplicationScoped
public class DevelopmentEntityManagerProducer {
...
}
{code}
Another very interesting usecase would be to enable specific interceptors/decorators only
in development stage. This could be used for debugging stuff that is only interesting
during development.
I think this could be easily implenented using an CDI extension that vetos beans that do
not match the active project stage. The only problem I'm seeing is that we will need
the JSF project stage in an very early stage during application startup (actually before
JSF started up). This means that we would have to determine the project stage JSF will use
ourselves.
The JSF spec describes that the project stage can either be set with a servlet context
parameter or using JNDI. If the latter one is uses, we could simply do a JNDI lookup in
the extension. No problem here. If the developer uses a servlet context parameter the
situation will become more problematic, because we will need a reference to the
ServletContext in the extension.
What do you think of this feature? Would it be useful? Any further ideas for the
implementation?
