Pete Muir updated CDI-44:
-------------------------
Component/s: Interceptors
Clarify that interceptors must be implemented using subclassing, and
clarify the behaviour of self-invocation
-------------------------------------------------------------------------------------------------------------
Key: CDI-44
URL:
https://issues.jboss.org/browse/CDI-44
Project: CDI Specification Issues
Issue Type: Feature Request
Components: Interceptors
Affects Versions: 1.0
Reporter: Stuart Douglas
When implementing interception using proxying the behaour of self invocation is quite
well defined, if a method is invoked on the proxy it is intercepted, if it is invoked on
the actual bean (usually through self-invocation) it is not.
When implementing interception though sub classing this is much less well definied, and
the only way to track if an invocation is intercepted or not is through a thread local
flag. At the moment in weld this is reset when a call is made on a client proxy, so if we
have an intercepted bean A and a SessionScoped bean B and A invokes B when invokes A the
second call to A is intercepted. If however B is pseudo scoped, then the second invocation
is not intercepted. The correct behaviour here should be specified by the specification.
