Pete Muir commented on CDITCK-137:
----------------------------------
I've re-read the spec, in order to try to construct a clear picture.
From 6.5.3
"The container must ensure that every injection point of type InjectionPoint and
qualifier @Default of any dependent object instantiated during this process receives:
• an instance of InjectionPoint representing the injection point into which the
dependent object will be injected, or
• a null value if it is not being injected into any injection point."
From this, it is clear that for the injection point under discussion,
whether it is null, or a valid InjectionPoint object depends upon:
a) that the decorator it is injected into is a "dependent object", and that
b) that the decorator is being "injected into an injection point"
Given that 8.1 says "A decorator is a managed bean." and that the decorator is
dependent scoped, (a) is clearly true.
I can find no direct statement to say that (b) is true, otoh, I can find no direct
statement to say it is false. Therefore, we have to fall back to secondary evidence.
1) Given the overall design philosophy injection points, it seems reasonable, and useful,
to have them work inside decorators
2) It is reasonable to assume that the decorators and injection points should work in a
consistent fashion - either decorators should be visible to injection points (and thus be
able to inject injection points, and use them) or be invisible (and thus have no effect on
injection points, such that they behave as though the decorators aren't present)
3) Given the existence of the InjectionPoint.isDelegate() method, the spec clearly intends
you to be able to identify that the bean is being injected into a decorator's delegate
injection point. If we were to assume that decorators are "invisible" to
injection points (so that the injection point for the decorated bean is in fact the
client), then this method would always return false, and thus be pointless.

Key: CDITCK-137
URL:
https://jira.jboss.org/browse/CDITCK-137
Project: CDI TCK
Issue Type: Bug
Security Level: Public(Everyone can see)
Reporter: Gurkan Erdogdu
Method : testChainedDecoratorInvocation
In this test, TCK tests the injection points of the Decortor delegate. But it seems that
this test is specific to Weld. In our case, we manage decorator stack via single delegate
not via injection each decorator reference to DecoratorInvocationTest
