Re: [cdi-dev] Portable decorable Bean<T> instances
Hi,
yes, there is no portable way.
It is a similar situation as was with interceptors before InterceptionFactory was added.
[impl 'details']
In principle, to implement this, you need to create a "wrapper class" around the
object which is to be intercepted/decorated.
If you provide a custom way to create the bean, it is very difficult to create this
wrapper on-the-fly.
Even the solution for interceptors has some shortcomings and flaws and decorators seem
even more complex (less restrictions on how does a decorator look like).

Subject: [cdi-dev] Portable decorable Bean<T> instances
Hi,
When adding a manually constructed Bean<T> instance using
AfterBeanDiscovery.addBean(Bean<?>), or using the
AfterBeanDiscovery.addBean() method and the BeanConfigurator, the resulting
bean can't be decorated.
This is because seemingly CDI expects the create() method of Bean<T> to
locate the decorators itself and apply them to the instance it returns.
Using BeanManager.resolveDecorators one can obtain the Decorator<T>
instances, but am I right that there's no portable way to actually apply
those decorators to the bean instance?
Kind regards,
Arjan
