Subject: NEW ISSUE: Dependency reinjection
TARGET: Java Common Annotations and APIs specification section “@Reference” DESCRIPTION: The description of the @Reference annotation does not specify what
happens if the wire changes after the component has been instantiated. One
example of a place where this could occur is for a composite-scoped component
that exists at the domain level. The target of its reference could start off
unwired (and thus would be null). A later deployment could deploy a <wire
source=”” target=””> element which provides a target
for this component. PROPOSAL: In the above scenario, when constructor-based injection is not being
used, the target MAY be reinjected. This would be marked as “MAY” behavior, since it would not
be required of all runtimes. However, the developer who is creating portable
code needs to know that this reinjection may occur. Other scenarios where such reinjection may occur is TBD. Note that
reinjection should never occur for a conversational-scoped component that is in
middle of its conversation. |
